next question how do i cure it ?

 

Either the correct spec turbo for your engine or capping the boost until further up the rev range so it doesnt surge.

 

i had a problem with boost last year ie no control=40psi+& no surge what so ever right upto the red line 8200rpm stu repaired my ecu this year & i also done cam trigger mods had cams timed with dti gauge to cam spec & now it surges all the time even when i unplug air injectors could it be cam timing ??????????.ps boost is capped at 32ish psi now but its real hard work to get to that point cos of the surge
