i dont think we really lost much down low. our stall is stupid loose(~5000rpm) and it was hard to roll into it at exactly the same pace. if you look at the boost level in the lower rpms we are down on boost. with a real load and the boost up to the same level i think we would be up on power for that entire graph.

Why so loose?

And how much boost on that run? I thought it was an 8 psi and the 21 and 17 numbers were the manifold backpressure.

I just bought a used 02 Z06 cam for the turbo 5.3 going in my dads '72 and give $90 for it. The yellow LS6 spring that work great with it are only $60 new from SDPC.
