PFI Speed

THE BEST PERFORMANCE SHOP and FUELTECH TUNING IN COLORADO. I have referred more people then I can count no one has had a bad experience. These guys have decades of experience in the industry they always go above and beyond to help people! They touch vehicles 99% other shops would turn away they truly care about their customers and their projects.. There passion for automotive performance reflects their work ethic and knowledge. HIGHLY RECOMMEND

If you have your average stock honda lawnmower build, pfi is your shop If you have spent any amount of money on quality parts and want to make sure your build actually runs for an extended period of time??? Stay far away from PFI Brent is the nicest guy on earth but you wont get quality work from him (if hes even the one to tune your car when you get there) unless youre a popular youtuber If youre just a regular guy that works hard and wants to have a nice honda, this aint the place for you

What an amazing group of people! Whatever you need done, import or domestic, PFI will take care of you. Our dyno and tuning session went really well and our truck is finally running like it should. Thank you PFI!!

Had Jamie helping me with remote tuning. Got me in fast, very flexible, reasonable cost. We were about 90% done when my fuel filter collapsed. Ended that session there as I didn't have a replacement on hand. After I ordered and installed the new parts. We rescheduled and now today just finished up the tune. This is my first build, only 25 yo. And yet he still took the time for us little guys. Loved every minute of the experience and my camaro drives absolutely amazing.

I’m not sure what’s happening with PFI. But before, the quality work was great, tunes were awesome. Now it seems like the quality is not there anymore. I spent $9000, and the type of quality that I got in return was awful. Definitely don’t recommend this place anymore. I had to get my car tuned twice because the first time it wasn’t right, and after driving the car for about 500 miles, the tune went back to shit; can’t go past 4000 RPMs, zero boost leaks, checked everything on the car. I contacted a tuner, and he looked over the car, and he told me this was terrible work. Most of the coolant lines did not have any clamps, leading to coolant leaks; the battery wasn't relocated, wiring was terrible, and the car had 3 oil leaks after a fresh K swap oh and kt doesn't end there supposedly missi
