Hello, Just for others. I just got mine running from these maps. But only the 2.8xxx code. My car would barely run on the 2.6 (too rich). Don't know why. Anyway, I hope to post my tune soon. I have a 74 260z l28et, .40 over je forged, 1mm metal gasket, p90, 450cc rx7, 40psi, 60-1 turbo, z31 direct coil, ebay intercooler, ms2 3.57, autometer wideband. Recently converted from nistune-It sucked!
