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

2007 Chevy Impala SS w/5.3L V8

Reviewed By John S (Hamburg, NY) Reviewed for a 2007 Chevy Impala —5/21/2010 6:46 AM

After hearing that others did not have much luck getting any additional HP out of their Impala SS I almost didn't buy the unit. When I recieved it I was shocked at how easy it was to install becasue I've purchased others for other companies that were a real process to install. That said it only took a few minuites to install. Then came the test, my car was taking 5.9 seconds to get from 0 to 60 and now after checking the numbers several times I am running 0 to 60 in 5.0 flat, the power through all gears is amazing and the shift points are much crisper. As far as mpg I won't know until I get my foot out of the gas.
