So I just got back to tuning my Mustang and I'm having a hard time getting the top of the MAF curve leaned out. I've got a Pro-M MAF that was supposed to be calibrated for 24 lb injectors, but I've had to lean the curve out to look more like the stock A9L 5.0L curve. At higher flows though, my wideband is still reading anywhere from 9-11. I can keep leaning out the top of the curve, but it seems odd to me that I'm having to lean the curve out more than the stock MAF curve. Is that ok, or do I have something else wrong?
