Is there any larger/less restrictive AFM we can rig up or even a MAF unit that wouldn't require an ECU reprogram?

RE-EGI obviously.

so then, if we were to stick with the stock AFM and ported it out to flow more air, say 15% or 20% or something, then we should theoretically (assuming that worked in the first place) be able to increase our injector size by the same percentage and then not have to worry about doing any ECU work, as it'd still be sending a correct signal... The only time you'd run into difficulties is when your injectors and AFM weren't equal variance from stock, yes no?

 

i believe someone here was working on wiring up the MAF from a 5.0
