Should the STFT's really only fluctuate that little even at idle or crusing? My STFT sometimes will fluctuate a lot, but the car runs good, and I've tuned the MAF pretty spot on.

Send me a log as soon as you get HP Tuners so I can double check your fuel trims seeing as you drove 1200 miles north of here LOL. I also have a fix for both the P2237 code and a way to smooth cat heating mode out quite a bit.

I think I took a slightly different approach. I do not touch the cat heating main tables only the cat heating idle tables both intake and exhaust cam. It works better IMHO. Comes out of cat heating mode a lot faster and is much smoother and quieter on startup.
