Excellent Throttle Response & Nice Little Boost in Power

Super easy to install by simply plugging into the ECU. I've taken it for a test drive and noticed a nice little boost in power, but what I really noticed is the delayed throttle response is cut in half! It will clear the check engine light, but I caution you do NOT think that everything is "ok". It doesn't increase gas mileage and I am ok with that. Definitely a must have if you don't intend to do much to the engine.

Don't make a mistake, get a stage 2

Almost got a stage 1 but after reading reviews I realized I would not be happy with a stage 1 considering I had a K&N cold air induction and a cat back Flowmaster exhaust, I was right. The stage 2 is what I woul have expected from a stage 1 so get a stage 2 if you want not to be dissappointed.

I really haven't seen alot of difference except when I first installed it. The engine idled down and a little more torque but not much better in gas mileage.
