Default What MAF for 30lb injectors

Trying to tune a 90 5.0. I have put in 30 lb injectors and still seem to run lean. I have had a buddy of mine tell me that the MAF is wrong for the injectors. What is or would be the correct one for these injectors? Thanks

What mass air do you have now and 30's seem a lil big for your mods.

I have part # m-12b579-a70 MAF sensor. I was having problems running VERY lean and burning valves. Thats why someone suggested to put the 30's in.

It should not matter what MAF you're running if you get a tune on a chip, the correct way to use larger injectors is with the tune telling the computer what injectors you have as opposed to getting a "calibrated" MAF.
