Supercharger PROM... no FMU
OK, I upgraded my injectors so I can try to supply enough fuel to my motor without using the FMU. I now have Lucas 42.5 lb injectors. My fuel pressure is 50 psi with the vacuum line off. The FMU is set to its leanest position, so it only adds 1 psi fuel for each lb of boost. I'm still using the MAF sensor. I was just wondering how high others have had to go in the "Power Enrichment vs. RPM" tables of the PROM? I have mine up to 50% now, and I'm still lean. What experience does anyone else have with playing around like this?
