MY ROD GOT OUT Member 434 Member For: 14y 8m 20d Posted 26/07/13 09:47 AM Share Posted 26/07/13 09:47 AM Same actuator? Sounds like its dumping boost as the standard actuator may be stuffed. Just a guess, as most will say go see a tuner/mechanic Link to comment https://www.fordxr6turbo.com/forum/topic/85744-massive-flat-spot-after-changing-turbos/#findComment-1410177 Share on other sites More sharing options...
