How does the v2 model compare to the v1? The previous owner of my car installed the v1 Sprintbooster. To be honest, I hadn't driven a stock Crossfire prior to buying my car so I can't really make any real comparison. All I know is that the throttle is extremely touchy......much touchier than any car I have owned in the past. I am also used to a to a traditional manual car so getting used to drive a high hp car lacking a clutch pedal was like learning to drive all over again.....lol. I have gotten used to it since purchasing the car but there are times that I still feel as though it's too touchy for my taste. I am considering selling it and buying the adjustable v2 model so it can be a bit more civilized when need be.
