Any comments on the cam, 228/238 .571/.581 115+4? Should the lift be more? Too much split? I think the duration is OK because you want to keep the overlap down in FI applications.

Is this intercooled? If it is, why the low compression? At 8lbs of boost, there is where his power went.

The compression is too low for such a small amount of boost.If had 9.5-1 comp I would expect probly 70-100rwhp more.8.5-1 is turbo compression.
