Get a short runner or siamese the TPI. Same with restrictive truck heads with small valves.
A big cam is a mismatch.
Turbo cams do not have a street machine idle.
You could be making a lot more power with less boost. Most of your gauge boost is pure head and intake passage restriction.
i do have a semi converted lt1 intake, i need to finish the welding on it to use it, that intake would deff be better but has its own airflow issues
im not using small valve truck heads on mine though the 882's arent much better they are atleast better, the head shave been cleaned up , and the tpi is ported but im not going to drop 400 bucks on a set of runners to siamess them
