GBDoes what it says I purchased a stage 2 chip for my 97 pickup and noticed a difference right away. Power, throttle response. Haven't seen a huge change in gas mileage yet probably because I have been enjoying the new feel of the truck a bit much.

GBIt cost me a $200.00 repair bill It cost me a $200.00 repair bill for my 2007 Cadillac Escalade. The performance chip interfered with my EBS and Stabilitrak system. It affected my ride, and my braking, and after taking it off and throwing it away I feel like I'm riding in a completely different car. Whatever difference it was to supposed have failed to materialize after 1,500 miles.

GBGreat Product, Great Service I bought a stage 2 chip, and though it was a significant power increase, it caused some surprise redline downshifts with my transmission when letting off the gas after full throttle. Contacted customer service who were very helpful. Replaced it with their JDM stage 3 chip and it is performing flawlessly. My Crown Victoria is now positively FEISTY!!!
