I plan on running 7lbs of boost out of a t3/t4 turbo on a 1997 420a. (RS 2G Eclipse)
I have the Walbro 255LPH installed without extra voltage mods, along with Bosch 24lb fuel injectors.
The kit I bought which I'll link at the bottom, has an adjustable fuel regulator (1-15 psi) to max 140.
Will I be okay with running just this and what would be the best pressure to set it for?
or will I need to replace it with a FMU?
