Hey guy, working on a buddy's car which he converted to return system with a 340lph pump and aeromotive regulator set to 43.5 psi. This is a turbo car seeing no more than 12 psi. I know the mustang has low mass and high mass fueling. I'm wondering if there is anything special i need to do other than adjust the maf scaling to hit my afr targets. Any settings need tweeked etc.
