Is it a stock PCM (stage 0)? Staged PCM's will not have emissions monitoring points enabled and depending on which state you live in some testing centers may or may not detect this.

Sounds like a problem you would get with staged PCMs.
But you can also send your PCM to DiabloSport and they can reflash it for you. I ended up having the exact same problem as you and before buying another stage 0 PCM, I sent it to diablo and they reflashed it for free. Problem solved.

If you're tuned it's likely that the emissions monitors were turned off. You'll need to flash the original tune assuming your diablo made a backup of it. @duster360 would likely be able to help or at least point you in the right direction

I don't think he's been active in the forums for a few years now but he's definitely still around. I don't want to post his info on here so you'll have to go to his website to get it www.needlesstorque.com
Either way, I wouldn't bother him with this issue. You already know what you need to do. If you successfully restored your original backup via your handheld tuner and your emissions monitoring points are still disabled, then you either a) have a staged PCM, i.e., stage 1 or b) your original backup did not restore correctly. Like I said contact Diablosport and they can reflash your PCM for you. I sent them a stage 2 PCM to flash to stock (stage 0) and they did it free of charge. All it cost me was shipping.
