First off: twm itb's on gsr with 550cc injectors, pro2's and s300. for some reason it doesn't want to idle when attempting to tune on the tps table. it requires excessive amounts of fuel and idls surges irratically. It is very inconsistent and the tps is reading 7% with the throttles fully closed. the twm tps on these is not adjustable so what else can i check. i guess first things first so how what do i do about the tps?
