<a href="http://homepages.nyu.edu/~jod204/charts_data.xls">here are charts/data</a>

bottom line. i'm only getting about 143g/s MAX (datablock 002) and about 13.3ish psi boost (no more than 1900's

so...;where to go from here?

these were done at 55deg. 3rd gear...oh. and some were done with the 3/4 throttle teqnique- u can see my throttle position during the runs on the charts and some were done at WOT...no difference....

ARRRRGGGHHHHH

also there is a procedure in bentley to diagnose your maf while idling with vag-com.

iut looks like you might have a bad maf. check the airbox first though. then do the bentley procedure.

Have you tried unplugging the MAF and see if performance improves??

Check for boost leaks, and also try unplugging the MAF

Tongpo~Dr. Evil

but i wouldn't assume that would affect it- if anything i would imagine seeing more air coming through

Tongpo~Dr. Evil

since requested is relatively equal to actual boost. if it was leak i'd see a big variance in requested boost vs. actual.

possibly maf

Tongpo~Dr. Evil

if indeed disconnecting MAF works out, i can assume it's either dirty maf? since a dirty maf will throw a dtc?

I just logged my airflow and only got 17.16lb/min ~130g/s

50* ambient, about 70-106 intake temp

this is also with a "Pocketlogger" on my palm logging general OBDII stuff. My friggen Vag cable hasn't come in yet. I don't know how accurate this thing is. My airbox pre-screen is clean though.

Tongpo~Dr. Evil

i mean, if we're both getting roughly the same readings then APR is bull****ting with pwoer gains (i mean i've read vag readings of giac chip with a 2100 -1.1bar from two seperate cars with same relative readings- and they're doing it no problem)......or thers something wrong with both our cars....did you measuire boost by any chance?

I am only doing this from a Pocket Logger on my Palm. Not VAG-com. Like I said before, I dont know how accurate this is compared to VAG. But my boost gauge hits 15-16psi no problem. The software for the 2001's may push more air than the 2000's.
