Will MAF change mess with tune??

I have a ported maf with a dyno tune. After some checking I believe my maf has some problems. If I go with a screened oem maf will it affect the tune or will I be OK?

Yes it will change it slightly. But I have absolutily no idea why you would have gotten a dyno tune with an unscreened MAF.......

I didn't. The car had been dyno tuned at Carolina Auto Masters when I bought it and the MAF had already had the screen removed

every MAF is different. so yes it will change a tune. do you have to tune for it...no.

as long as it's withing specifications you'll be fine. you may lose a HP or three but you'll not even notice it.
