Possibly.. does it pop off when you're pulling through the revs or is it when you change gear?
I've read back through some of your posts and it sounds like noone is absolutely sure what your car has or what it is set up for. It may even be something plumbed in wrong if whoever fitted the turbo made a booboo. Also the duty cycle for N75 in the remap for the k03s is going to be COMPLETELY wrong for the k04-001 if that's what it has - it will overboost like crazy if the duty cycle isn't pulled way back in low range.
