Complete noob on tuning (mechanical ENG not electrical/controls lol) but do I need to rescale the MAF if I keep the STD rotofab? Let’s say I kept the STD rotofab and changed the snout and added a 103mm TB. Obviously the car is going to get more air, and would need more fuel, but I would think the MAF would still read as normal. I’m more familiar with Gen III cars and IIRC at WOT they went into PE which ignores the MAF and puts in a fixed amount of fuel. So I would think I would need to add more fuel in this scenario right? “Rescale MAF” I would think would need to be done if the diameter of the inlet tube changes (aka Big Gulp) or am I wrong?
