Bigger injectors, better maf?

[kas14slider]

Hi guys, I was thinking about getting bigger injectors for my KA-T. I wanted 550's. Do I have to get an upgraded maf if I get these injectors because right now I have sr 370's and on WOT to get the AFR's in the 11's my safc hi throttle settings range in the -40% to -30%. So I would have to turn down the fuel even more but you can only go to -50% on the safc II. Will an n60 maf be good enough or should I get an n62 maf if I wanna run 550's? I do not plan on going over 300hp.

Any insight would be appreciated.

Thanks, Alex.

The SAFC will be able to trim the the 550's, since they are twice the size of the stock units.

The MAF doesn't increase the range or adjustability of the SAFC at all though. However, you should ditch the factory unit since it's not good for much more then 250WHP give or take.
