I meant to say that LMAFs and all Ford MAFs are not calibrated. That's not to say they can't be calibrated. What EMS were you using to tune? Just wondering why the calibration wasn't done in the tune.
I was using the factory computer in my 98 and an SCT chip. Remember that this was 13 some years ago and a lot has changed since then. If I were to build the same car today it would be worlds different.
