Hello, I am having a problem with the boost surging/cutting out when I get on it fairly hard. It is very noticeable and you can just tell there is something wrong because sometimes it does it bad and sometimes not so bad and between these is a huge difference. When it happens it basically sounds like a rush of air happens...running strong then that rush goes away for a second..power loss...comes back power back. The only time I really notice it is in and past 3rd gear when I'm hammering it down pretty good. It has done this for a long time and I can't figure it out. The car is a cobb stage 2 with uppipe, downpipe, turbo back.

This has finally annoyed me to the point of fixing it so any ideas of what it could be would be great!! I have the accessport but haven't messed with it much past the point of installing the map, so any assistance with logging data to help pinpoint the issue would also be nice.

I'd start with cleaning your MAF.
