I am still confused. If I have the mods in my sig, and i am buying a Ford 80mm MAF with 24lb injectors, will that be fine? Or should I just stick with the Ford 75mm MAF with the stock 19lb injectors? The car seems like it could run better.

this pdf file right here may confuse some but it will explain exactly what your EEC-IV EEC-V is thinking and what its programmed to do and you will learn that yes some performance parts are scams, if you can unlock your ECM you will unlock hidden power also look at the Adaptive Control section

so, what I got out of this is no matter how big a MAF or injector set up the car isn't going to perform any better by "calibrating" everything to the stock brain in the computer. So, if you increase the MAF leave the 19# injectors, have some one build you a chip for the computer that tells it has a larger MAF then you have made a REAL increase in cfm. Is that it in a nut shell? It's like taking a 750 cfm carb and rejetting it because it runs too rich , when all you've done is make it a 650 cfm...back to stock(ish)
Okay im new to fuel injection. Im planing on a rebuild on my 302 and i want to upgrade the air and fuel delivery. I want something that is gonna perform good at the strip, anyone have a idea as to what i should go with for a MAF and injectors, im also confused on if im gonna have to get my computer reprogrammed or not.
