Is it running higher than stock boost?

BA valve springs are notorious for being weak, especially after

a few thousand km's. It could be valve springs struggling under

high boost and valve floating, it kind of shudders under WOT.

If you let it fall back to idle after it happens, and it runs rough

for a bit, that's probably the problem.

I changed the coils and all my problems went away.

here is a photo of what was wrong with the coil;

if u see anything like this on your coils replace them and u should be right.

good luck mate
