I am running the 8MM with a P5 and 086 pipe on a full mod and all I can say is wow! The key to tunning for me was setting the idle screw back to factory settings, as I had previously moved it all over the place. I big thanks to Joe Alessi for setting me straight! This is absolutely the best engine I have ever owned.

On another note, anyone know where I can pick up some more p5 plugs?
