I know what you mean Moparbust. I'm VERY skeptical myself. But I decided to buy one because everyone say it will eliminate the throttle lag / shift lag that really pisses me off. I'll let you know what I think in the spring when I can put it on.

I am interested to know if anyone else can corroborate what RIOT said about the ECU mapping also remapping the throttle. Looking down the road, I will probably do the ECU tune. But I suppose I can sell my SprintBooster when I do.
