Hey Bob,
Just a small correction the 3.33 pulley is a 9psi pulley. The 2.875 is a bit over 10psi.
Also what bypass valve are you running because the stock Bosch unit blows off at 10psi.
And another thing what do you mean about the fuel cut off at 6750? I can pull all the way up to 7500rpms, but the bypass starts releasing pressure at 7,100rpms
What other mods are you running besides your SC
