SOunds like a fueling or ignition issue. Get it to a propper mapper to diagnose. Dont take the chance.

could be surging...

if its only a whapping big turbo thats been fittd with no attention to other things, the turbo coulbe be producing too much airlow than the engine can consume and causes it to stall/ surge,, common on cossies running big turbos that havn't been properly set up.

:yeahthat:

But some more info on your setup would be good. Can you explain more about what happens, what revs etc. does it accelerate ok after the juddering?

when i bought the car it had been stood for a while and i had trouble with poping intercooler pipes, sorted that though with mikalor clamps. She is running T67 fitted by dude, 650 injectors Greddy ecu blitz controller fse fuel regulator, like i said it drives normally to 0.4/0.5 boost then it is like all the boost is lost then will come back over again so very jerky. But sometimes it will boost normally upto 1.5 +, even though the controller is set to 1.2 max.
Thanks in advance:rolleyes:

sounds like a bit of a boost leak to me.. if its hitting 1.5 bar and the boost cntrll is set to 1.2, that would suggest overboost??
wich could come from a slight boost leak

No.

Don't try and do this yourself. GET IT TO A ROLLING ROAD.

True but it could be quite a few things from the symptoms. Best get it setup adn it wont cost you an engine.
