If you're hitting the g/cyl limit in the tune, you have no choice but to counter-scale the fuel side (IFR) so you stay in bounds of calculations. AFC (raw frequency limit) is a totally separate thing so you need to have that figured out first and then you can scale maf vs IFR how ever much you anticipate you need. So if you have a fixed freq AFC, the first thing is to make a base maf table to work with that. Unfortunately that part is not a simple multiplier (because the maf table in the first place is not linear). The best way I know of to get to the right place there is with a polynomial plot formula. PRJ paul was kind enough to give me an excel document that produces a new maf table for you with your desired scale factor. That's the trickier part. If you are already ok with your base AFC-modified maf table then you just scale the maf table down in proportion to the injector flow rate and then you have maf numbers that are understated (which is what you need) and injector flow rate numbers that are overstated but it all works because you're lieing the same amount both ways.
