VelocityS4

I removed my intake (for other installs) and reinstalled it, and now my peak MAF is 234 G/S, and FATs time is .5s slower... no codes and no CEL... APR 93 Octane chip

MAF hits 231 at ~5600 rpms, and it seems to level off there for the rest of the RPM range all the way to 7k...
the intake is an S-flo with darintake hole... maybe the MAF isnt seated properly on the airbox?

Thanks for any help

ambient temps the same, or were they way higher today in the daytime?

what'd your IATs look like?

SLPR S4

air flow was about 225 gps on stock and now I regularly hit 265-270 with Darintake and stock panel filter. The altitude here is about 1000' above sea level.

I used to have the ITG but tossed it b/c I blew 2 MAFS and you have to clean them for good flow. Never again ... the hole in the airbox gives you more gains than that filter.

I went to a stock panel filter and have been on the same MAF for well over a year. )

Sounds to me your MAF is almost dead but not enough to throw a CEL or the MAF is not fastened correctly (the MAF doesn't fit well to the intake tube). (

stock IC's, ambient temps almost the same, what is IAT?

IAT = Intake Air Temp.
