Is that with the standard exhaust?  You usually get a bit of popping on the over run with an aftermarket exhaust as the standard one absorbs a lot of that, but if yours is stock, sounds like the fuelling is all over the place!  Popping is basically fuelling exploding in the exhaust and not related to the Wastegate directly.

When I say popping I mean it's loud enough to scare people on the footpath Lol  surprisingly it's quite easy on fuel 35/38 is quite normal.
