Maggie Tb upgrade
been a while since I’ve been on. I currently have a 04 gto M6 with a TVS 1900 SC. Stock heads and cam. Running shorty headers.
Move been kicking around the idea of going to a 92mm Tb with larger MAF and larger intake tube.
Would it be worth it?
also I recently took off my catless mids and installed my catted mids, the car feels like it picked up torque and pulls harder. Is this common?
