Hi All, I thought I posted my question previously, maybe wrong place. Here goes; '97 M3 track car only, S52B32 motor, M50 manifold, OBDI w/ 413 Bosch Red Label, race exhaust (3" S.S. Straight thru w/ magnaflow muffler on stock M3 exhaust headers. Intake side has trac control TB removed, aftermarket smooth intake tubing between TB and manifold, stock 3" MAF, cold air dinan intake. We put in 24 lb. injectors (don't know if that was unnecessary), the motor spends much of its life at full throttle. Looking at the tunes that came w/ the WAR chip, any recommendations which one, or is there a better tune out there? We discussed going to a good quality 3.5" MAF and larger intake piping to go with it. Our thinking is that with the M50 manifold, and straight thru exhaust, maybe we should increase intake diameter to take advantage of better exhaust breathing. I love opinions.
