    Remember that when you change the tune you aren't 'Emissions Ready' until you complete the required drive cycles.

    Turn the key to 'on' (not start) and watch the CEL - if it blinks ten times after about 15-20 seconds, you are NOT 'ready'.

    I'm in CT and I put my stock tune back in before I went though emissions. Not sure if I needed to do so. For something that will take a few seconds to do, it's piece of mind to ensure you won't get a failed test because of it.

    I dunno man. I put my stock tune in right before I went to emissions and failed (not enough cycles or something like that)

    My battery died over the winter as well, but it had taken a charge back and I used the car quite a bit before attempting the emissions test.

    I would bet money that if I hadn't put the stock tune in I would have passed the first time.

    Yeah, you need to make sure you drive around for a while (like 20 miles) before you are "emissions ready" after you install/uninstall a tune. Made sure my engine light wasn't flashing before I went.

    Erik, good info for the next time I have to go through emissions. I'll just leave it in from now on.

    Gotta remember there are those whose cars will not even run on a stock tune.They have no choice but to leave the Predator CMR tune in.

    Mine passed the tailpipe sniffer test with a superchips tune installed (with the Sidewinder/high flow cats) the first year, and I've left the predator tunes in ever since.

    I failed emissions last year as my 'cmr tuner' turned off my rear O2's (with shorties? wtf?) so I went back to a tweaked 'canned' tune and have never looked back. Car runs much better too.
