[QUOTE="1320 Junkie, post: 14078867, member: 96955"] Your not explaining it correctly. The calibration aka Maf flow curve has EVERYTHING to do with who tuned it. Those fields are modified by Steeda according to the ops original post he has a tune in the car from them so if they didnt input the proper maf curve (aka a true 26"in/hg flow bench 36 point curve) and just scaled it with a "ball park figure" his boost reading will be off.

I recommend autometers digital series..or aeroforce [/QUOTE]
