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.
