Ditto Gilligan,
Just put TBS needles in and found the same improvement at mid throttle. Still a little flat before mid though and plugs look lean. I'm trying a shim tomorrow to see what that'll do.
Also found the screws needed to come out to 3 1/4 turns. Trouble is I've re set the screws and fitted the shim at the same time, so i won't know which one makes the difference...
