Not sure why your not getting top end power, is your fuel filter clean? Do you have a stout governor spring? What RPM will it turn sitting still unloaded? Do you have good airflow through your intercooler, any restrictions? I know in 5th your going to have more volume flowing through the engine.

Fuel filter is a few weeks old so I cant see it being bad again..... Not sure what governer spring I have in it. Guy I bought it from said he changed it already. My Rpm guage is being wacky.... It shows that it can turn 4000Rpm but I do not believe that. That's unloaded sitting still. Airflow should be pretty good id say. I have 2 sharp 90's that are going to be changed this weekend but I don't forsee that being the problem either.... Running no airfilter in a clean area doesn't seem to make a difference either.
