I can’t see it too well, but it looks like the tq and hp are on different scales, and the tq is not in ft/lbs....... its in nM.

Yes its in nm, i think i found the fault : one rocker is very loose and also think in cold engine the clerance should not be 40 on cold engine be 50, hopeffully i can take it to then dyna pack fast and see again..
