UMMM... nope.. if it is at 580hp now at 8-9 psi.. right?? at 20hp per PSI that would be 700 hp... add'n in that 6psi. with the right tune and fule I am sure it will take it. I am sure you can add maybe 2 psi with out swaping any tuning.. GM will expect hot roders to swap pullys... so 620 with nothing but a pully swap...
I was able to add 3psi to my GTP before it needed a tune... I did have to put in a high flow cat though.. it did not like the extra boost with the restricted exhaust.
