thanks for the reply. it was a while back when i done the scans. I have a Scan 2 KAL EQIUP by ACTRON. it was at 44degrees WOT in neutral. i also was getting system rich codes. i never done any thing to the car, only CAI/CATBACK/FREE MODS/ IAT TRICKER (52 degrees IAT) its 100's out here in summer. it was a couple months ago. well i did another scan today, no IAT tricker. i got around 38degrees WOT in drive, 15-18degrees at idle and around 33degrees cruising at 1200rpms. is that ok????

WOT in neutral ....YIKES!!! Not a good manuver. Always scan at wot in a gear ( I use 2nd rolling into in with my A4) .
Something doesn't add up. You should be seeing anything over 28-30 and several degrees lower if you've never had a custom tune.

You risk damaging things by revving the engine that high in neutral. Scan it while driving, and review the logs later.
Cars will typically have more timing at part throttle than at WOT. Adjust the part throttle problems to help alleviate driveability problems. Adjust the WOT timing to control power & knock retard. I personally think 33* at WOT is a bit much. Even if you're not getting any knock, it's unusual to get the best power with that much timing.
If you want to revert, either go to the dealer and have them reflash your PCM back to stock, or have someone with good tuning software reset your tables back to stock by comparing them to another cars calibration. That car should be as similar to yours as possible, btw.

I'm running around 29 deg timing but its also pulling -5 deg retard when i hooked to the computer plus my cats are clogged not really sure what kind of power i should be making.
