I've just done this on a AUY 115 the map sensor is 3 bar instead of 2.5, the maf housing is 80mm and the intake piping is also larger on the 150, I replaced all this.
I ran into issues which I put down to the turbo, bad lag, and not reaching full boost.
Tried a smoke leak test, tried adjusting the stop screw and testing with group 11 ( could never get over 110mbar? ) shortened the actuator arm which helped a little, tried running off map and maf tune, deleted the egr and asv and pipes so the n75 runs directly from the T of the tandem pump to eliminate vac leaks, tried a 150 ecu with stock map, 130 ecu and the stock 115 ecu running 150 linearizations and all tuning maps duration ect.
I did upgrade to a front mount and 2.5" piping but I believe this has no role in bad turbo lag which in turns causes black smoke low down.
Let me know how you get on or if you run into any issues as we may be able to help each other.
I have also deleted my egr valve and cooler.
