Default Injector/Maf

ok this may be dumb, but ill ask anyway. There is a chance that my injectors are flaking out, or maybe the maf, its hard to tell, but what im wondering is if i decide to just replace them whats a good injector to go to, and what about a maf?
because if im going to replace them id like better than what i have, even if the gains are minimal to none, make sense? are 24pounds a good start? dont even know where to begin with maf...

Need to get the issue diagnosed first and FYI, bigger injectors/MAF give NO gains at all

didnt think they would, cuz im pretty sure im not maxing out my injectors lol. But thats the thing, the injectors or the maf are the suspected villians...but so far no difinitive answer because the car has problems but not enough to pinpoint where they are coming from.

Check the maf first. If your maf is toast, then your injectors will seem like they arent working right. So try testing the maf voltage and see where that gets you. If youre gonna get a maf, look around for a lightning or 03 cobra maf. Then get that calibrated for your injectors and you should be set. Then if it starts acting up still, then check your injectors. Thats what id say to do anyways.
