the guys at the shop are very buzy but the out come atm they think not confermed if afm or fule pump, should know on monday

Why would it be a blocked exhaust? He doesn't have a cat and the thing dies, it's not just down on power.

sounds more like blocked exhaust mate, had that with a fair few turbo motors

this is very common on hotwire a/f meters, i would have cleaned this first as well

I would put my money on an Airflow meter/ air leak problem.

Start with cleaning the element with alcohol because they can get gunked up. You may be hitting the boost cut with a confused computer.

Check again that there are no air leaks from the back of the airflow meter to the inlet manifold. Also check you have all the fitting plugged up on the inlet manifold because there are a hole heap of them that you don't use.

could be a timing issue??

ok well it doesnt have a cat converter and new fule filter new fule lines , the motor is all standard inc the ecu

anyways it just got dropped off at the shop so any bets my bets on fule pump but realy i dont have a f###ing idea

o one more clue in first gear if i give it full throttle it gets some big bangs out the exorst

Try checking your cat converter. If its blocked up a bit it will let the motor work to a point, then when you start boosting there is nowhere for the gas to go effectively choking the motor.

is the actuator or the wastegate sticking/stuck open, we had a problem similar to this at work on a xr6 turbo ute
and that was the problem

the actuator...

It will more than likely be the fuel system. start with new fuel filter (if you are using a directional one don't play funny buggers and put it in backwards)

run some injector cleaner etc in the tank.

maybe hotwire the fuel pump and ignition (use the existing power wires as a signal to turn on a relay that has power directly from the battery)

ummm... reset ECU (disconnect battery -ve over night overnight)

perhaps it might be worth seeing if it smokes when it "dies". if it smokes it may be a lack of compression (rings are shot) if it doesnt then it suggests there is not enough air or fuel.

maybe take it for a run without an air filter.
