Sounds bad, turn the boost down. Check fuel pressure at wot be sure it rises 1:1 with boost.

Check plug gap also, make sure its not open to much.

What does the Power logger show when it starts to pop?

Check your cam sensor. Look at the locator tab for sheering.

It shouldnt be popping. If its breaking up a little, then I would suspect spark blowout. Check FP like mentioned above.. That would make it pop.
