"If you need your truck fixed up and sounding good, I really suggest them. Also customer service is A-1 and the staff is really helpful and nice."

"Got it tuned, by HPF. I won't speak bad about communication or support with them. They're very helpful. But I've only had my truck 3 months, & some ticking started happening on my driver side thinking it was 1 of my new ls7 lifters, than I realized after i removed my head, pistons 3&5 are gone/missing a piece. I was shocked, but 1&7 are starting to go missing. I'm sure on my passenger side is screwed too. I was told. It was due to detonation from the tuner."

"Frank has been very informative. He was able to tune my truck and have it ready same day. Very honest and cool ppl here. Highly recommend"

"Cesar and Frank really help me out. First off they had a great rate for their dyno and squeezed me in right as they closed. Next, I had some trans issues and got it rebuilt and they pulled out and reinstalled my trans. They did a fantastic job and even washed my car. Frank communicate pretty good with when and they charged me right in the ball park of what they said they would. They did a real great job with my car and I would take it back there again. My car is a 2014 Cadillac CTSV"
