2012 CBP FG4
Steve from E-Tunez told me that their go to is an overbored TSX TB (K24A2 06-08 / 64mm+4mm). It has the same current with a good idle, no codes thrown.I agree. Maybe just getting a shop to bore out the stock TB will be good. Also, maybe somehow change the circuitry of the TB. We did switch the a few of the components, but nothing helped. Maybe I just have to look into more.
