It's a VF620. The kit is advertised as maxing out around 6.5psi. I have not made any changes to it. My recent dyno confirms the psi rating. It showed 6.6-6.7 max at 8200rpm. Pulled 550whp in 98°F air temps. Car has 100 octane gas (but not tuned for 100), reduced cats with an Akra Evo X-pipe and a simple straight through (with resonator) custom exhaust.
