Sprint booster??!!!

[JJCRU23R]

After reading your posts, it doesn't actually look as though this sprint booster is false advertising. Actually its kinda like people are thinking too much into what this thing says it can do! It may trick your ecu into thinking your stepping harder on the throttle, but that was kinda the point! If you want to put your foot down as normal and feel your engine rev higher than usual then spintbooster is doing it's job. Don't think I'd pay more than 50 bucks for it though..

Actually it seems like the seller/manufacturer is making exaggerated claims about what it can do - the majority of the people in this thread are skeptics, and the main one spruiking it is the seller themselves.
