you read the "tuning the right way guide’ which promotes PE hacking. i didnt need to read any of that. i learned by trial and error. You have had software longer then anyone around here. Why did it take you 5 yrs to get a grasp? you admit when you dont know something? come on now man who are you trying to pull the wool over?
you beleive SD is a crutch but tuning 101 of 411 pcms states disable MAF and tune in SD to dial vehicle in. MAF in the 411s are error correction factor. if the VE table and the corresponding parameters in the tune are dead nuts the maf has no place. the later models use a virtual VE table and use maf more then the 411s…thats little more info for ya to read up on.
