Why is the Maf's range different between these files. File-Pull was when it came in and 17-Silverado-v5 is what I've been working with which started as a factory file uploaded from AcDelco TDS. I noticed its pegging the maf range around 9600-9800hz, is there a way to copy the labels and extend the range or why do I see other files where the Maf reads upwards of 14500hz and this is a factory file started with and its capped around 9600hz. I haven't found any answers so time for a post.
