I made 2 more rwhp with 2psi less boost on my new built motor with same h/c/i setup and same mods. This sound normal? How much boost are people making with a 5 psi pully?

Heads are not ported......... how about exhaust? LT's?

Heads not ported stock exhaust manifolds. Im sure its something simple but I know for sure when we had it at JLP it 15psi with around the same temps. Im just not grasping where the 2 psi goes when its the same setup as before and almost same weather. I thought belt slippage put all the belts and ten is new.
