Any one ,, No ideas Pleaseeeee.

 

Maybe test your coil packs? ECU?

 

Do you know how much you're still boosting? If your wastegate port isn't sufficient enough you still might be creeping. If this is the case, depending on how high you're boosting you'd probably want to get your injectors flow tested/cleaned, as well as rewire your fuel pump.

 

You think carbon build can caused? OR Intake thermo sensor ?
