Worth every penny!

Reviewed By Brian M (Nashville, TN) Reviewed for a 2013 Chevy Impala —3/18/2017 11:30 AM

I love it! It makes my impala preform like I expect it to and more. I installed it the same day as a drop in K&N filter and my car sounds awesome. I deffinetly recommend this to anyone. It made my car fun to drive again. Not sure yet on any mpg +/- because I can't keep my foot off the pedal. I was worried about passing an emissions test but it passed no problem. Biy this, you won't regret it!

My car runs the premium fuel programing with no knock on regular pump slight ping at part throttle 89 octane cures it all.Definitely more responsive, drivability improves, shift firmness better removes speed limiter as well mileage is harder to judge, it did not get worse I just haven't had a real chance to check precisely if you drive the car in the torque curve where it improves the engine performance it isbound to improve
