Maybe they ported it too much and its bleeding boost. Or another prob may be the flapper arm is getting caught on something. On mine I found that the flapper arm had been bent slightly and it may of been rubbing on the exhaust joiner, so I grinded the joiner back a bit to give it full freedom of movement again.

obsty Member 26 Member For: 22y 27d Location: adelaide SOUTH OZ Posted 06/09/10 07:19 AM Author Share Posted 06/09/10 07:19 AM its weird because when it happens and you back off and then accelerate again its fine.Had engine rebuilt and problem only started about 4000km after. Did you have to pull turbo back off to find problem? Link to comment https://www.fordxr6turbo.com/forum/topic/70373-boost-problems/#findComment-1037852 Share on other sites More sharing options...

When the actuator opens the spring pressure isn't strong enough to close. Also with the bigger flap it takes more spring pressure to shut so when you back off it closes and the boost controller keep it shut unit it get to the correct pressure.

obsty Member 26 Member For: 22y 27d Location: adelaide SOUTH OZ Posted 06/09/10 12:19 PM Author Share Posted 06/09/10 12:19 PM so it could be the actuator? too soft?

I think the standard actuator on the FG is around 8 pound or something near that. Try 12 pound actuator and see if that helps.Maybe even try 15 pound.
