Ok, had to sit down and actually put this in print, your ems is PFM!!!! (pure f____n' magic!!!) please excuse the language!! Not only was your service amazing, (3 day turnaround) but the bike actually runs too good!!! I fear that I will be receiving some moving violations very soon!! Seriously this product is amazing, I am a mechanic/tech for mercedes for over 40 years, and know my stuff, and My stuff says your stuff works!! Smoother idle, crisper throttle response, just plain faster, and seems to run very cool, that's hard to tell as its still cool here in San Diego. I am on a few web sites, and your product is raising questions/eyebrows as to its claims, let me just say I have sung your well deserved praises all over the cyber world and will recommend it to all that I come in contact with!! I wish you much success with this product. In my opinion, it's a home run!!”

“This product (Precision EMS) is simply amazing! It does everything it claims to do and then some. I first installed it on my essentially stock ’09 FL and the product worked great. The real proof came when I completely re-built my own personal engine as a 103” using our ported heads, Crane 1-3005 (.615” lift) cams, exhaust, ect. and the system reset itself by just going through the initial start-up procedure again. After 35+ years in the business I can say that this is truly a great product! From this point on I will urge all of our customers to use this product when upgrading their engines as it completely eliminates the use of a dyno and risk of an inexperienced tuning technician.”
—Dan Thompson, Hot-Shot Motorworks

“Got the ECM yesterday, plugged it in and did the throttle reset procedure and, after it warmed up, took it for a ride. All I can say initially is “WOW”! What a tremendous difference. Much better throttle response, and better acceleration all the way through the RPM range. Pretty dramatic improvement. Given this I will in all likelihood not need that 103” upgrade I was thinking about. This bike, 2009 Street Glide, is pretty strong as is. Thanks again for your help in getting this done!”
—Mark

“What a great product the monster big bore kit, I love the power and torque of my 124 on my road glide so much that I also got your monster big bore kit to build my street glide to a 131 thanks again for a great product, and your informative pod casts.”
—Randy Laws

“I just had my first ride after getting your Stage II completed on an 2005 Dyna. The dyno tune changed everything and I will have to say this is now a monster compared to what it was.... Kudos to you all and thanks for the new motor.”
—Dan Box

“...I bought your monster big bore cylinders for my 1990 bagger and I couldn't be happier with them. I have ordered alot of parts over the years and I have never had the support like I recieved from your staff. I thank you very much for sending me exactly what I needed for my bike.”
—Steve Millican

“I have a 2001 Nighttrain with one of your 131 kits in it. I love this kit!!!! My motor has 98,000 on it with this kit. It goes in the snow, the heat, the rain almost every day. Boy it was nice bolting on the new kit. Kudos to you all for standing behind your products. I was and am still very impressed by the way your company does business.”
—Lee Krejci

“Thank you for the great machine work on the cylinder heads. Recieved them in very good condition, and they are installed on the bike. Runs great, very impressed!”

“The podcast are the exact type of information that I am looking for. Expecially being new to the Harley industry. Currently I'm deploy to Iraq with the Wisconsin national guard and I past my free time watching, learning and taking notes on your podcast. This helps me out tremendously on what direction I want to go with my bike.... Thanks, and keep up the good work, cant wait for the next podcast.”
—SGT Sazama, Alan

“Just a pat on the back for your podcasts. Extra big slice of raisin pie to Brian. Truly enjoy hearing easy to understand factual info in a no nonsense forum. I am upgrading my 03 FLHTI from a 95 to 103 this winter. Steve Miller at Ace's & Eight's in Mason Ohio is doing the build and just sent my new crank to RevPerf to be trued and welded. It's great to be able to get the down & dirty on the process. What a service! Count on me to 'spread the gospel' and encourage other riders to investigate Revolution Performance's products & services. Thanks again.”
—Reno

“I am having one of your 124 kits put in to a 07 e glide and can't wait for the snow to go to try it out. I had one of your 98 kits in a 01 e glide and the bike was incredible. Boyles in Old Town, Me did/ are doing the work. Hope I'm as happy with the 124 as I was with the 98. Great product.”
—Joel Fitzpatrick

“The people there were great and I asked many many questions and traded email till I had the cam, bore, valves, springs, rockers and revs I was hopeful of!”
