my cars surging on boost and i have tried every thing to locate the problem
auq 180
checked for split pipes leaks, no leaks on smoke test
replaced turbo compressor
replaced puck
replaced rv
checked the waist gate rod for movement, can move by hand with force sprayed with wd40
checked the timing and replaced belts
no fault codes
next thing to try is the boost controller valve
any idea's?
