Sounds like your suffering with boost spikes, have you removed all your Cats ?. Checked for leaks on wastegate pipes, boost solenoid pipes. You could fit a Dawes valve this will stop your boost spiking if everything is O.k

yes all cats gone..will check the other things you have mentioned...thanks....

 

Might be worth checking the spark plug gap, mine had similar symptoms to yours and the gap was way over, set them to 0.7mm and the boost peaks and holds where it should now!

 

ok mate...hopefully 1 of these things will sort the problem
