J.RandomS4 (oinked)

My friend just purchased a 2000 M6 S4 with brand new K03s. I'm looking to go back to stock so we put my X-chip in his car today. I have the identical setup - k03s, now bone stock.

Long story short, his car is SLOW. I could take him stock without much of a problem, so something crazy is going on. We unhooked the MAF and the results were pretty much the same.

His car makes no noises which would tell me TBB or BPVs, and we tried to eyeball the TBB and it looks new. He's on the BOSCH MAF.

Please compare these for me. The log ending in "Jared" is for my stock mapped car, while the log for "Joel" is his newly giac chipped car (on fresher K03s!)

Thanks for the help. I got into my car yesterday though and it had gotten much faster. Is there any reason why the chip would not have been working until the following day?

log again and see if it looks any different?

a couple weeks ago i had 1,2,3 cyclinder misfire codes as well as one for fuel too lean. And of course the cat's were overloaded because of this. Could all this stuff be linked and if so what could be the problem?
