    2009 WRX Hesitation Under Boost

    Hi all, I just joined this site and it looks like there are a lot of knowledgable people on here. I have an 09 WRX with 23.3k miles on it, I have a Cobb AP flashed currently to stage 2+AEM 91 severe low wastegate. I live in the chicago area and the temperature has dropped a bit since winter is about here. I have an AEM CAI, and catless exhaust with the tune. I was driving the other day and just as I was getting under boost the car starts hesitating in 3rd gear and kind of sputtering and the acceleration was pretty bad. I think it is because it is colder out so tonight I tried to log it but didn't get a great log since it just hesitated a bit and the exhaust sounds like it backfires when I let off the throttle. I have no trouble codes at all, it drives fine when I am not trying to get power out of it and I don't really beat it up that much so I'm thinking I was over boosting or on the verge of it or maybe a boost leak. Can someone advise me on what could be happening?

    Thanks

    1) You don't have the proper mods to run a Cobb base map
    2) You're logging too many parameters
    3) Log to CSV files, so it's easier to view
    4) Uplodad to Google Docs (set to public)

    Take a new log, with only the following:
    RPM
    Load
    Boost
    WGDC
    DAM
    FBKC
    FLKC
    Ignition Timing
    Throttle
