You need to tune your MAF curve and fueling like you would for most anything. I adjusted my injector size by 30% to make it seem like they were smaller so they flowed more and then adjusted my maf curve and target afrs from there. Once your get your curve near perfect you can just set your targets. ALWAYS SCAN FOR KNOCK AND AFR.

Makes sense... not to thread jack, or change the intent of this thread, but why are the MAF curves necessary to change? I have done a ton of tuning on my current setup, but have never changed the MAF curve. AFRs on the wideband show up just fine and the car is showing extremely close to the target AFRs the ECU is commanding (which I set).

Also, how do you adjust the injector size? what table is that in in the tune?
