Injectors cutting out as turbo boosts
I have recently been having an intermittent problem with my car experiencing total fuel starvation as the turbo starts to boost.
50% of the time the car is fine, the other 50% it will experience the details outlined below.
Symptoms:
As the car boosts (manifold vacuum pressure exceeds atmospheric pressure) the injectors cut out, then cut back in on deceleration.
As the injectors cut out it is necessary to back off to stop the car from stalling.
The car is currently at my mechanics and has had a dyno run so I am confident the injectors are the problem, just not sure of the solution.
Any help or suggestions would be greatly appreciated.

Definitely not just a hesitation, if I try to drive through it the engine will stall.
The car is still drivable if I accelerate gently and is not experiencing any other issues (idle is normal, starts up easily).
No modifications have been done to the car recently with the problem just starting without warning.

Might try what Cake said. Swap in a known good one. Got a orifice in your boost sensors line? Try that also. See parts ficsche for Orifice.
Seems to me if it were an injector the coil in the injector would go **** up permanently, not part time. Same with a ECU injector driver.
