RepinS: when your transmission isn't slipping whatsoever, then it would be around 2500rpm. But mine is closer to 2900rpm/3000rpm on a day when the car hadn't been driven for a while. There is no illusion.. and because of all the mechanical parts on our cars [not electrical], just the TPS sensor mod, will NOT give more power anywhere. It'* kinda like a tune up, nothing more than extracting the power that was already there. It'* kind of hard to explain, especially at 6:30am.
It does not give a "performance mode" all it does is report the ACTUAL voltage to the ECU, so it knows what to do with it. This doesn't really do anything more than that.
