I have a 2008 lmm that was previously tunned but went to flash over it with a good stock file then flash a modded file on it and now it sets a constant p0101 code. does have a afe airbox on it but no loose clamps or damaged areas. during my idle it will read from 20grams/s to 150grams/s and even swapped in a new maf sensor on it still same issue and truck is doggy even on a 80 hp tune
