Well I recently purchase this mod including both TBG's and i couldn't feel difference because i install my vibrant exhaust, strup header the same day. Couple of the days ago my Injen Cai started rattling badly once I start moving my car. The coolant hose is still touching the intake so i need to fix that as soon as i can. I want to hear everyone opinion including the people who has this mod and the people who had it and sold it for wherever reason. P2R tested this mod on a stock car and dyno pretty good. But does the TBS works well with I/H/E? So its worth having it or not?
