Turns out it wasn't a boost leak. It was actually the wastegate arm - when I initially put the turbo back together I counted threads and measured the length of the wastegate arm to return it back to "stock". Turns out this isn't accurate enough for EWG vehicles.

I had a friend of mine who is a BMW tech run the EWG calibration procedure and turns out my eyes and measurements were off by 2.55mm! I'll be having this fixed next Wednesday by BMW and be back on the road datalogging!

So you mean to tell me that the PS2 EWG turbo needs a wastegate adjustment before you install it on the car? Sigh!!!
How do you know where to adjust it to?
