it would be great if HP would let you know if it worked or not? I never get to rev limiter rpm before the begin button lights up again.. no matter how fast or slow I rev the damn thing! Verry frustrating! 2006 SSR tune E40 4.8L.
ounce I thought maybe I hit the rev limiter before it went back to begin, so I shut off the engine, and turned it back on.. no dice, it is unclear waehter I need to trun the key allway off? My switch is weired came out of a 07 van and it seems to kill igntion and power to the pcm when I switch it off even just the first notch.. anyway would like to know weather it needs to be all the way off or just the igntion off
