Ok, here's the deal. Decided to upgrade my setup to T28, bored maf 4 bar and 370 inj. I realized that when I took my ECU out, it said that I should have already been using a bored MAF, 370inj @ 3 bar. Ok cool. I get the MAF bored out to specs, throw it back on the car with the original setup and now this bitch runs like a raped ape, but idles like **** and runs way to lean. So was the ECU not really programmed for a bored maf or what? Any suggestions? HOw long should it take for the ECU to adjust?
