I bought a trick flow upper plenum and a 70mm bbk throttle body. I wen with the 70 because going for lower rpm power and the 75 just seemed alittle to much, o crap i sound like a puss. Anyway the plenum accepts 75mm and the throttle body is 70mm. This makes for a poor transition and "less power". My queston: should a bolt it up and leave it alone, port match the TB to the plenum, or just get a 75mm TB?
