    Bought stage 3 for our camaro, within minutes of installation decided to order stage 3 for our truck. So far extremely satisfied

    I purchased the 40 hp chip for my 2009 Pontiac Solstice. I loved the difference in performance that it made. I decided to buy the 60 HP chip for my 2015 GMC Sierra 4.3L V-6 because I tow a 21 foot travel trailer. Wow! That truck runs so much better! It idles better. The throttle response has improved. And, the transmission upshifts better than it ever did! Also, it doesn’t downshift as often when I’m pulling a grade while the cruise control is set. My MPG has increased from an overall average of 17 to 20 so far. So happy that I did this!

    I ordered the stage 1 to try it out and it works great no issues at all. I would recommend this performance chip.

    This chip is insane I installed it so easy plug and play so much power I shit my pants and then had to really unleash power to fly home and clean up. As soon as I jumped back in I let her have it, I am talking I opened the gates and let all the horses out. Crazy shit my self again. So other then the clean up of my bowels all over I give the chip 10 out of 10 two thumbs up. You a fool if u don’t buy this. “Let the horses out to play”

    I definitely noticed a gain in horsepower but nothing with my mpg. Not disappointed at all.
