I just finished rebuilding my 89 325i with an Ireland Engineering 2.9 Stroker kit, HP cam (street/race), Ireland shorty headers tuned Schnitzer exhaust, FSE adjustable fuel reg, Miller MAF and war chip, custom 19# Bosch injectors, Bavarian HP ignition wires, Carbon-dynamic cone filter, etc. After much experimentation I set the idle fuel pressure at 42# and although it lopes a few times at startup it levels put after 3 or 4 lopes to 900 rpm. This is a very nicely done motor and runs strong and smooth, however, 1st gear it feels like it could accelerate about a third better, like it is starving for fuel, however, when I raise the fuel pressure even to 44# it runs poorly in the other 5 gears. Obviously it needs to brake in, and only has 700 miles on rebuild, but I think it could do better. I am a bit of a perfectionist and when I say it is about 85% there, however, I have a '88 m3 with a Stroker kit and a split second maf system, and piggy back ait fuel control for different gears (1st, 2nd gear and so on). It runs great, and can say it runs perfect. I like the Miller Maf system and want to keep it. What do I do to get it up to 100% short of switching the entire system? Please help, any suggestions (that are reasonable) would help. For example, we live in Washington state and I can take my car to Miller in Vancouver; would that be best???
