John S from Hamburg, NY said, "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."
