wrench87 Go to the FE forumn and find Joe Craine. He does a complete intake porting on the intake manifold. The intake looks like jewerly when done and flows alot better. Some of the ports are 8-35 cfm off from the rest. It's worth ever penny. His turn around time is about 1 week. This removes the lean running cylinders. The polishing of the ports also helps because of the upper dry intake we run from the FI system.
