Have you enlarged and ported the waste gate, or is it stock? You can also add a standalone waste gate, but you would have to machine a somthing for inbetween you exhaust header and the turbo.

The wastegate is stock.  I haven't looked into how much you can improve the series V wastegate, but I'm betting it won't be enough.  At this point, I don't even know if I'll keep the turbo. 

on the other issue - how about, move into the the hangar? or borrow an RV or camper...

Can I give up my job, and leave my wife too :-)
