MAF and injectors

Would anyone know if I can run 42lbs injectors with a MAF thats calibrated for 24lbs injectors without having problems?

Even with a properly calibrated MAF for 42# injectors it probably won't run right. Just too far off from the curve programmed into the computer.

Plan on a tune.

What do you have that justifies 42# injectors?

24's would work but i think make their cycle rate higher than you'd like for reliability, but it would work all day long. You really just have a basic(no offense)GT40 setup. I'm running 30's with a Cobra Maf cal'd for 24's and it makes my eyes burn(non tuned). 30's would be right where you'd need to be with "room to grow" IMO, 42's are not necessary at all and will hamper performance within its allowable parameters.

Haha! That's how I ended up with my 30's trading up lol. And I misinformed, I have a pro-m 80mm cal'd for the 30's but its way too much because my Cobra ecu(tune)is set for 24's.

No clue to be honest. I'm in the process of getting everything drive able and then I'm going to go get it tuned.

24 lb'ers will be more than enough for your combo.

There is no real need for 30's or 42's.

Like Matt said the stock ECU can not really handle the 42's to have good driveability and good WOT.

Your car with just basic bolt ons will be right on the money with the 24's.

I agree. 24# injectors with the 24# MAF will be fine for what you have.

What MAF do you have?

And, just because, might want to try reading this:
