what next

Well I decided not to sell my TII and am now considering further modifications..

I've taken care of the exhaust with a full 3" racing beat one. It's great, but it's almost too much. I'm boosting too high and besides a FCD and a walbro fuel pump (rewired), I don't really want to think about fuel mods anymore. I'm planning on porting my wastegate soon(this is on a s4 btw) and I want to know how big I can make the hole with just a dremil and without any excessive mods. Also with this new size what will the boost be looking like with just the exhaust (everything else stock) and assuming my turbo is in top shape?

Hopefully it will return somewhere around the stock level.. maybe not..

Anyway, my ultimate goal is to do as many "free flow" mods as I can and still be able to control the boost. That is if massively porting the wastegate will get my boost way down, I want to look into getting an intake, doing the TID mod, TB mod, maybe even porting the intake manifold.. but how many of these mods could I perform after porting the wastegate and still be able to use a MBC to turn the boost up to say.. 9-10 psi so I don't have to worry about fuel?

Thanks.
