I lost alot of top end power , starts high 2nd and it really loses rpm on 3rd. Don't know whats going on. I see the rpm start struggling up high. 1st gear is kick ass. I got a 85 mm bbk intake manifold, with a matching throttle body, headers, slp cold air intake kit. Slp lid. Smooth bellow. its a 6speed. Any ideas? it has spark plugs that are gapped 60 . Ngk they are pretty new. no cats .
