I just had my cam gears adjusted on the dyno this past Saturday. It was a good investment as well. Now I sit at 133 whp and, 126 ft-lbs TQ.
I dont think anyone has proven gains with this... Just better response... If u saw gains maybe it was dynoed on a diff day, colder car, other or with mods installed
