2001 Audi TT Coupe 225 APR 93 Chip Engine Code AMU

New airbox (TTDA)installed during TT-East. Started throwing codes (CEL as well as ESP yellow light on dash) that won't go away after repeated clearing using my VAG. Has anybody experieced these codes after having TTDA installed? The car still pulls strong. I spoke with Steve Schwing (creator of TTDA airbox) and rightly so he said wait a couple weeks and see if they clear out but I wanted to see if anyone here has had the same experiences.

MAF was replaced by dealer in September of 2003 when car had 35,657 miles on it; now have 49,000 miles and no other MAF related codes have been thrown and car pulls strong (APR 93 chip). Thanks for any insight!

car pulls strong, but does it jerk at high rpms (4K) w/ decreased performance?

Yes - now the differences are obvious now that I replaced the MAF. Much happier now.
