Rob and Dan,
This note is long overdue...sorry, I've been out riding.
Fella's I can't Thank You enough or even begin to tell you
how happy I am with my Road Glide, she has more power and
the ride, it's smoother then I thought a Harley could be.
Just goes to show ya, if you get the right people doing the
job - great things happen. Last year (2017) while in Mass.
for a bike trip, my friend (Jeff) let me use one of his Road
Glides. You did the tune on the bike, I rode if for 5 days;
1,500 miles (the ride wasn't just around the block) and I
was totally impressed with how she ran. Before I cam home
Jeff brought me in and introduced me and you and we talked
about what I was looking for.
I live in California
and was having some trouble with my 2011 Road Glide, plus
she was getting tired and lacking the power I was looking
for. So...I did was any Sane man would do, I sent my bike
from San Diego, CA to your shop in Mass. You and Dan bumped
her up to a 110, put on new suspension, then did one Hell of
a Tune on her. I can't tell you how much fun it was to ride
home from your shop to San Diego (Sept. 2018). I was having
so much fun, it took me almost a month to get home. I kept
checking the map, looking for all the twisty roads I could
Now, back home, I'm
tearing up the California mountains on this beast...she is a
ton of Torque, just what I was looking for. She make getting
up and down the mountains one hell of a good time. Even when
I have to get on the Freeways here in CA, she'll keep me out
of trouble with just a twist of the throttle.
Rob, just wanted to
give you the feedback after taking my bike to the track.
HOLY CRAP what a difference. The smoothed out fueling let me
ratchet throttle much more effectively, which let me hold
more speed through corners and smoothly accelerate out of
corners with less jerkiness. As the numbers show, I didn't
really have any gains on the straight, but where it counts
there was a massive improvement. I'll definitaly be
recommending your services to friends... and also may take
you up on doing another mapping with the baffling out to
actually get better top end. I'll see if I can get this
flashing process a bit more stable for next time...
wanted to thank you again for tuning my bike. On the ride
home I was able see how much better it runs.
It was worth every penny. I couldn't be happier!!!!!
Good Morning Rob,
I just purchased the
tool from you to install cams in my Chieftain and just
let you know how well it worked for me.
The quality of your
tool and ease of operating it is fantastic!
Your instructions were very simple to follow and made
installation a breeze.
I would HIGHLY
recommend your tool to anyone!!!!
Thank you again for all
Got it and it worked
absolutely fantastic! Thank you!!!
P.S. Your tool is
everything you advertised, so thank you. In this day and age
that doesn't always happen. I'm very happy and satisfied
with your product!!!
just got off this beast and I am telling you I am totally
impressed...when I was watching you tune this thing and I
seen the torque reading over 140 on the initial runs I was
thinking I can't be reading it right...then as you went on
and told me it was correct and impressive too...I knew it
was going to be worth the work you guys did to it...when you
were running the last runs I was watching not only the hp
and torque but the speeds were at 136 m...ph and was
thinking to myself thing is gonna be a rocket...it is! When
I'm cruising along in 6th about 2700rpm' 85 mph and just
roll that power on the goddamn speedometer needle drops like
it is a tachometer!!! Goes to 110 in a second like the
throttle is mechanically attached to the needle...I'm
telling you man this thing is awesome!!! Not only all the
excitement you can pick up from my words about the power but
the bike itself is so smooth throughout the shifting...it
handles like a dream...thanks to you and Dan for all you

Hey Rob,just a quick shout out and thanks again for the
I took the springer to street drags here in NY and got
second in class.
Would not have been able to do it without your work on the
SuperE. You did this In Abay if you need a refresh on which
It ran great! But I screwed up the launch and spun the wheel
on this final run.

Just got home from
Rob's Dyno Service with my bike. If you are planning on
adding a Power Commander or similar product, check him out
first. Was never really happy with those products and how my
bikes ran, even after paying good money to have them tuned.
Rob put in the time, money and took factory courses to know
these fuel systems inside out, which is why he is the only
one to figure out how to get into them and reprogram them to
make your bike run it's best, especially important if you
add exhaust, air cleaners, cams, etc. My bike is definitely
more responsive, sounds better, runs stronger and just feels
all around better. Indians, Harley's, Victory's, Honda and
others will all benefit from his services. We all pay good
money to have these bikes, don't cut corners or screw things
up, go to Rob's Dyno Service and get it done right.
Finally took my 2013
FLHTK to Rob after years of being unhappy with the dyno tune
provided by my Harley dealer. My gut told me my engine could
run better. I was not sure if Rob could help me because my
dealer told me my bike ran good and nothing was wrong with
my setup. Guess what? I was right and the dealer was wrong.
My engine idles, starts, runs and sounds like I always knew
it should. Give him a call, make an appointment and enjoy
the full potential of your Harley.
I just wanted to say “Thank you” for giving me back my
Freedom. I was at wit’s end, and in a state of depression
after spending thousands of dollars on engine modifications
on my 1999 FLHTPI with 198,000 miles on the engine ( all but
97 miles were mine. I ride a lot ). After getting it back
from the shop I got on it and it ran like “Poop”.
I was told about you and made an appointment. I am so glad
that I did. I arrived at the shop with the bike on the sled
in the rear of the cage, because It was running so poorly.
After watching you do your magic on the Dyno and seeing the
old girl hit 133 MPH, I knew I had made a good choice
bringing my bike to Rob’s Dyno Service. Once it had passed
Rob’s high level of standard, He asked me to take it for a
ride to make sure I was happy. I WAS MORE THAN HAPPY. I was
pissed that I had to put it back on the sled to bring it
home. I wanted to get on and ride. I rushed home took it off
the Trailer, and put a FOR SALE sign on the trailer.
Praise the Rob Swartz the “Dyno King”. I road my bike late
into the night, and to work this morning. I plan to ride at
least 30,000 miles till the end of the year. It runs like it
did when I bought it in 1999, but better. In the future, I
will be bringing the bike to Rob for any future engine work.

Rob & Dan,
A Million Thank You for making my 2015 HD 48 Sportster
absolutely Amazing & a Monster!!!! Words can not describe
how wonderful the experience was…. Between actually seeing
how the Dyno Testing goes and seeing the before & after
difference in torque, to the patience of working with me to
help me find the perfect parts to make my bike custom so
when I ride its so comfortable. You helped us save so much
money down the road and such a headache because without you
guys we wouldn’t of known where to start & probably would of
bought stuff that wouldn’t of worked. My husband was
speechless when he hopped on it to just move it, he could
feel a Huge difference in torque right away. Before it
puttered as you eased off the throttle and onto the gas but
now its so smooth and you let the throttle out and she’s
ready to go. For once in all the years I have ridden & had
to adjust to the way the bike was & what I had to work with.
It's wonderful to have a bike custom to work with me for
once! She looks nasty…She sounds nasty… She handles like a
beast and I’m absolutely in Love with her!!!!!! You will
defiantly be seeing us again to do Ben’s KTM!!! We will most
defiantly be sending people out your way!! Thank you
I wanted to take a moment to thank you for the tune on my
2014 Indian Chieftain. After hundreds of miles of smiles, I
can honestly say have you exceeded my expectations. This
bike is so much smoother with no flat spots on the highway,
great throttle response and the additional power is just
“WOW” ! The 126 Ft/lbs of torque is more than I imagined,
but, very glad to have it. I will keep telling all of my
fellow Indian riders that this tune is superior to any ‘Add
on’ available on the market. Rob’s Dyno service is tops in
this field !
I am very glad I listened to you and did not just start
throwing parts at the bike. We tired a good looking AC only
to learn it did not add any additional air flow over the OEM
AC. Glad to have the S&S AC. While I do have stage 2 OEM
cams, I will keep in touch as you find more and more
aftermarket cams that may help unleash even more for my
111”. This is just the beginning of a long lasting
Thanks again, Rob.
Rob & Dan,
A million Thanks for the suspension and lighting work you
did on my Limited!!!! When asked about who does the work on
my bike while my buddy and I are touring Colorado, Utah, New
Mexico and Arizona in June, you can rest assured that your
names and the name of your shop will be spread around the
Both of you are the best I have seen in the motorcycle
business. It is such a pleasure to work with technicians of
your caliber and moreover people with the passion for what
you do and the people for whom you do it.
Thank you also for taking the time and effort for delivering
my bike yesterday, Rob. I truly appreciate the service you
I look forward to future projects with you.
Just wanted to reach out and say hello and thank you for the
help you and Dan gave me building my motor last year. One
season and about 5k miles in and the bike runs awesome! Glad
I listened to you and Dan and followed your thoughts and
ideas on my build last year. The bike runs and pulls well
exactly where you said it would, where I ride.
I have given your name to a couple of guys that will be
reaching out to you to do some work.
Thanks again, merry xmas to you and Dan.
Just a courtesy follow up after I've
ridden around for a hundred miles or so... phenomenal work
Easily the best money I've ever spent on a bike.
Just wanted to let you know how pleased I am with the Dyno
tune. I've put about 400 miles on the bike since the tuning
and I absolutely love the throttle response in all gears and
the pull in the higher gears.
I've also noticed a reduction in heat against my right leg
and a reduction in vibration at cruise speed. Thanks for
being a perfectionist!!!
I just wanted to follow up with you and let you know I very
impressed with the dyno tune you performed on my Street
Glide last week. I’m amazed how responsive and crisp the
throttle response is. On top of the performance gas mileage
has increased and no more annoying popping at start up. I
also enjoyed the whole experience of watching you complete
the tune as well.
Thanks again. You’re a true professional. I’d recommend your
service center in a heartbeat.

PS: The ride home to RI was a blast!
Hey, just wanted to let you know how pleased I am with
my bikes tune (done 5/23). I have been busy and just
rode the bike Sunday. The throttle response is faster
and the bike runs much, much smoother all the way
through the rpm range with more power and pull. Even
shifts smoother. Best of all NO Pinging. All bikes would
benefit from a quality dyno tune.
I appreciate the personal attention.
Thanks again !! Ken Jesse
I want to thank you again for unchaining the animal that
lives in my motor. What a difference in the response, nice
and smooth. Only been on two rides since I was at your
place. Yesterday checked my mpg, I got 46. It was only that
one fill up, it could very a little bit from one fill up to
the next. I know I have to get you the bike and get it tuned
up. Jeff was talking to a guy about your services (had a
XC) gave him a card that you gave me. Talked to a friend that
also has a hammer, he is interested in possibly doing
something to his bike . Again thanks, keep up the good work
