Depending on how you've been running the engine you can still have pinch at 12 ltrs I know because my 1st 7 port still had pinch at around 10 ltrs.
Jesusaves what i meant was did the revs increase quite a bit or only slightly before cutting out they should only increase very slightly
I would probably try leaning the LSN by about 2-3 hours and richen the HSN by the same and see how you go also check to see what your Idle gap is like should be around 1mm no more

Thanks Adrian, My ideal is pretty low the engine will just ideal once up to temp, but no more 20sec then cuts out. As for the LSN is fairly lean already it revs up quite bit then cuts out after 3-4secs.
I'm going to try what Mark (Mr Massive Mods) suggested, this should do the trick.
Besides all the dramas I really like the Go engine, it’s the pinch that’s holding back the performance on the top end. Now that I know what my problem is/was.
