stutter on WOT

[automaticonlyspeed3]

Hey guys. i need a bit of help here..

I get stutter on WOT. its like a pulsing dadadada..
car runs great normally!

Ill post a log to help..

few guesses.. I got a spark plug that seen better days.. but again, the car runs fine during normal driving.

I might have a slight boost leak possibly..

engine knock spiked up to 5 during WOT..

not great with cars, but any help would be appreaciated.

Stock engine,
stock turbo.
bought freektune, just didn't get around to tuning it yet. so cobb at the moment.

1 don't run cobb it's tunes
2 a boosted car doesn't like spark plugs that have seen better days. Could be as simple as tightening the gap back up

3 fix the plugs and any boost leaks before starting the tune
