Default K, if its right before "GVWR weight" then it was made in 05 01

If it makes any difference, the screen on my MAF is not completely flawless flat. It waves very slightly, not alot, just barely enough to notice. Someone told me it matters the way the air hits the sensor.. maybe thats doing something? Again, its only a small dip in the screen, nothing substantial.

Default Don't suspect the screen yet, do you have another S4 nearby that you can pull the MAF sensor off

of for testing? I would like to see 260 minimum on your setup but some cars just read a little less for one reason or another it seems. You're at ~250 now w/o the foam filter... whats a FATS pull look like time wise? Be sure to go WOT ~3400rpms so you'll be at full boost by 4200.

The best(repeatable) time I got on APR Stg2 93oct(with RS4 ICs though) was 4.9sec at ~58deg/700ft elevation. I'm pretty sure with DPs and testpipes I could have cut a few tenths off it. I'd try swapping the hitachi sensor first though.

Default Ohhh!! Why didnt I think of that before?! Yeah I'll switch MAF's with my buddy and log a run

like that, and gain back my sanity as well. Thanks so much!

My FATs times were around 5.2 at around 55-60 degree's (MAF fine, boost, etc). Then when my buddy and I logged my car a little while later (about a month later, logged right after changing my EGT's) and discovered the MAF problem, we plugged those numbers into the FATs calculator to see that my time raised to 5.8. =(

Thanks again dude.
