Most people think of having a high performance vehicle dynoed, as did I. Josh had set up my 72 C10 with a LS, excellent job, and help me with some emissions problem with other vehicles. So, I have a 2004 K2500 4X4 Suburban I use to tow my Jeep back and forth across country. It always had plenty of power,but never had the performance I thought it should. It's a 8.1. So Josh said bring it in and let's see what I can do! Well I have been across country 4 times prior and just arrived in Colorado after having Josh perform his magic. I simply cannot believe the difference it made. I gained almost 30HP and the throttle response is amazing. So if you want the most out of your every day driver or tow vehicle this is the place to come to. I finally have the performance to go with the power.Thanks Josh

Been going to Pete for nearly 15 years now and I don't even know where to start. He has tuned my Lightning from when it was nearly bone stock, to now where nearly nothing is stock anymore. He has been great to me all along and my tunes have always been spot on. I have sent a few friends his way and they would recommend Pete in a heartbeat. Pete is the man, if you have a Ford don't hesitate to call him. I am sure Josh is unbelievable as well with GM's from all the dyno sheets I have seen. I should have posted this years ago but better late than never!

Great tuning shop in the northeast. Pete is one of the best Mustang / Cobra tuners on the East Coast. His partner Josh has established himself as one of the best Chevy in Dodge tuners in the Northeast. Excellent service and results. I've had several Vehicles tuned there over the years and have been happy with all of them.

Had a great time tuning my C6Z. Josh definitely knows his stuff and got it running smooth with great throttle response and power - exactly what I wanted.

Pete has tuned my cammed 94 Cobra and my 03 supercharged Mach 1. Could not be happier. Done right the first time both times. Well worth the three-hour Drive both ways. Thanks Pete.

By far and away the best mustang tuner in the northeast. Pete knows mustangs like a surgeon knows the human body and he went above and beyond when tuning my cobra

7/26/2022- I had Pete go over the tune on my supercharged 2002 Mustang Gt for some drivability issues. Pete worked his magic on the dyno and solved not only my drivability issues, but also squeezed some more power out of the car. Very professional and made sure everything was properly functioning before delivery of vehicle. I would Definitely recommend Performance Dyno for tuning.

Simply the best place to go. Been a customer for the past 9 years since I got my 04 Cobra. Pete has always taken care of me, and has the safest, most reliable, and strongest tunes you will find on the street. Don't trust anyone else with your investment, there is no substitute for Pete's work!

Pete and Josh are fantastic! Pete has done my 03 Cobra and my 13 Shelby GT500. Both are extremely professional and very knowledgeable. If you need a tune, no place better.

Performance Dyno was recommended to me by a few of my close friends who are car enthusiasts. Pete and Josh have done an outstanding job tuning my 2005 Mustang GT! Where other shops had issues, Pete and Josh were able to tune the car to get it to its peak performance. Their commitment to excellence and fair prices in an industry that often tries to 'nickel and dime' the customer is the reason why I drive over 2.5 hours to get my car tuning done.

Josh has tuned multiple cars for me. The guy is like a Jedi with these cars. He's incredibly knowledgeable with not only late model engines but the older classics as well. Its been a great experience bringing my toys to Performance Dyno!

I've known of Performance Dyno for years and have been bringing Pete Johnson (owner) many of my modified Mustangs for tuning purposes for years. Pete is a very knowledgeable tuner and a great guy to deal with. He will bend over backwards for his customers and is a great tuner. I have in the past and continue to recommend him whenever I hear of people needing tunes with their vehicles and looking for a great shop!

As a business owner I understand how important it is to take care of people. As my first computerized build, my car had me pulling my hair out. Not everyone drives supercars.... But when you spend thousands of dollars in upgrades, your corner garage won't do. I went through a series of attempts that left me overwhelmed and unsatisfied. I had some awesome local help, and a suggestion that led me to Josh. He overcame some mechanical issues .... Identified tuning problems, and pulled 30 horse out of an already tuned car. 5 stars isn't enough. But more than stars, it's about trust. Whether your ride is worth 5k or 150k , this is the place. Thanks Josh. You guys rock.

By far the best place to go for horsepower and torque graphs you can take home, car tuning and chips. Reasonably priced compared to similar places, and the people here are very experienced professionals that know exactly how to get the most out of your car. Many people come here after some other place messed up their car, but you won't have that problem here. I would rate them 10 stars if I could.

Josh went out of his way to make time to fit my car in. He had to make time for me twice because of a problem with my build. My car could use some touch up idle tuning but overall I'm happy with my experience

2005 GTO, 228 comp cam, SLP long tube headers, k&n cold airAwesome job today. It can be tough to schedule an appointment, but Josh eventually got back to me. It was worth the wait. They know what they are doing and do it very well. Josh will talk to you and let you know the changes he makes and the reasons while he's tuning. Car runs like a beauty.

Pete helped me get my tuned straightened out on my Whipple'd 05 Mustang GT that was having trouble for years! I had taken it to a different tuner up in NH before but paid almost twice the price for no results! Can't say how happy I am with the results from Pete and the price to boot!

Brought my 2017 Dodge charger R/T in to have a performance computer installed and tuned. The difference between stock and tuned was amazing. 93 tune added 80 extra H/P, shift point adjustment made the charger a beast. A MUST FOR YOUR DRIVE.

Pete was extremely helpful and knowledgeable about my truck and definitely went the extra mile when I ran into a few problems with my truck (01 Lightning). I had to drive an hour and a half to him but we ll worth it. Thanks Pete
