Excellent Throttle Response & Nice Little Boost in Power

Reviewed By Clinton J (Mascotte, FL) Reviewed for a 2004 Chevy Trailblazer —5/27/2017 12:54 PM

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.
