MAF question again. Howdy, I have a lightly modded 98 t/a. I've been running a GMAF and recently a couple people told me that it might be hurting more than helping. I've still got my stock maf with screen and all if need be. My question is, should i put the stock maf back on or keep the gmaf on?
If it helps my (minor) mods are... Free Ram Air, EGR delete, Whisper Lid, Holly powershot filter, no cats, 02 simms, cutout, borla(which ever i feel like using at the time), A4 with 3.42's. Thanks in advance. (yes i did a search, didn't find quite what i was looking for tho
)

Re: MAF question again. Thanks for the responses. Guess i need to save up for the dyno. Just payed tuition for this semester and work has been slow... may be a while.
Thanks again.

Re: MAF question again. You need to A-tap the car and check L-terms.If the L-terms are +'s then you are hurting the tranny since it drops line pressure and will slowly burn up the clutches.Thats why most A4 guy's recommend staying with the stock screened MA and add a MAFT to lean out WOT.

Re: MAF question again. I have the GMAF and did dyno before and after. the after included the MAF and a lid. I went from 317 to 325 rwhp with those two mods. there was between 4-10 additional HP throughout the curve.

Re: MAF question again.
Should have tuned it. GMAF is good for up to 10-12 rwhpwith mods and tuning.
Then, it doesn't let tuners do their job once they try tuning the car to adjust.

Re: MAF question again.
On my '98, I had a lot of pinging after installing the GMAF. Ended up going back to the stock MAF.
Also could have a flawed calibration on GMAF. In production this happens you know!

Re: MAF question again. Thanks again for the responses. Think i may stick the stocker back on for now. What if i just use the ends from the GMAF but the stock sensors?? or is it the screen and big rudder thing i need...
