Stock turbo, stock actuator (cut down for 10psi stock boost).

I agree with you matt, but with a 3" exhaust, and 2.5" O2 housing, I was hoping to be able to maintain the boost uptop, the pressure in teh exahust manifold can't be too much because it would cause boost creep wouldn't it?

The only thing I can think of is the turbo unable to hold uptop with the engine. Although according to the turbo map (last time I checked was a while ago) The turbo should be able to make 28lbs/min and still be pretty efficient (70%?).

Thanks all.
