Boost issues always are. Could be simple /could not :-)
Start by checking the Turbo (see if your Mech was right) Remove the inlet rubber boot feel the compressor centre/bolt for play; Axially is critical but in/out is important too. There should be None. Amount of play suggests just how bad it is. Too much and the turbo will Screeeech as the comp impellor rubs the housing .. Not Good! Turbo oil seal is another issue. But the resulting fog bank is usually self indicting evidence.
Hitting Fuel cutoff suggests that boost is there.. just uncontrolled.
Possibly the turbo actually is bad and doesn't readily spool?
There are other possibles... once the turbo has been examined.
