• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

2nd that motion.

FYI - My Monte is stock and I added a HFC early this last July, parked it for the winter early/mid-October. Never threw a CEL yet. Granted, not to say it won't. But I think I will have the PCM tuned before that happens.

Though, there is a none-PCM altering method used by a lot of folks with a HFC. Involved modifying a Sprak-Plug anti-fouler and spacing the O2 sensor out of the exhaust stream. Cheap, easy, and something I was considering if I had that problem.

It's a common thing to do with BMW's. And costs like less than a couple bucks IIRC. As for the HFC's...not saying yours has, or WILL...but it can happen...its been addressed a few times with a HFC throwing a CEL because it flows TOO well.
