#565, "RE: Has anyone figured out why our cars lean out at 4000 RPMS?" In response to In response to 4
95Esi, I've connected the FMU back to the manifold now that I have the SAFC. I've only installed the SAFC though. I haven't put in my 440cc's so all my settings are at zero. I just got my car back from my build-up not more than a month ago so I'm still taking it easy. Want to be extremely sure I do a good break-in of my engine and new clutch. I've got a recalibration kit for the FMU to drop it from 12:1 to 6:1 though once I drop in the 440's and start to really turn up the boost.
