Halltec MBC,

if i put on a O2 DUMP will that solve my problem, that would be really loud though?

or would i be better of with an exernal wastegate setup??

Yes, in my case it did solve the problem with my old setup (ported small 16G/BR 2.5" exhaust without cat)

A welder modified my o2 housing to dump the wastegate gaz externaly. For 100$, it was money well spent.

I have an O2 dump right now and im getting a lot of boost creep with my new EvoIII 16G. O2 dump doesn't really help much but porting the waste gate flapper to open up farther and portin the whole just a bit will do the trick usually.
