FI on a Stock Block

[JVENOM]

is it safe to run S/C 8psi on a stock block gt with a safe tune...
need some input?

yeah just dont push more than around 400rwhp on a safe tune and u should be fine

Yes, 8psi should be fine. Some people are running 10psi on a conservative tune but it's about the same results as 8psi with a slightly more aggressive tune.
