Guest suprageek Posted August 7, 2015 Share Posted August 7, 2015 It was always fitted and boosted fine to 1.2, Paul whiffin also said you can still boost to 1.2 with the ring fitted and boost controller Quote Link to comment Share on other sites More sharing options...

Try turning the duty up on the boost control Quote Link to comment Share on other sites More sharing options...
