I'm not sure. How high does it want to rev? At what RPM does it feel like power is dropping off? IS 4500RPM your upper limit right now?

It will run like a small port 13B with power between a stock 12A and the SE. Non-op aux ports won't cap rpm limit, just takes longer to get there.

Ah. That's how my engine would run with an NO intermediate plate.

yeah after about 4k it revs freely with no misses but it seems like theres no powerband. I have a full exhuats, dlidfs, cold air intake, and the car doesnt have the power i would expect at higher rpms. As soon as i order some manifold gaskets im gonna get my sleeves clean to rotate again and fab up a pipe outta my exhuast. If they do open should I expect getting back alot (maybe 30 hp) ive lost?
