    I meant that it made it ping with the wider squish. Keep your squish at .040".

    yes it pinged like mad with the old map. I have it kind of sorted but Fred will fix that tomorrow.

    no problem mate. I doubt it will go as good as last run but you never know. It seems to like the drop in CP but time will tell. I've pulled the 58 and just running the 50 which seems better to me but my butt dyno has been so far wrong many times.

    her you go Hilly bit late sorry but the dyno guy ain't much of a computer guy

    Both sheets in std as I can't find the SAE sheets

    Ignore the peak number of 122 as it spiked hitting the rev limiter which I had set lower than Fred expected

    so lets say 119 hp 121 ftlb

    Old sheet before I knocked the compression down and opened the squish.

    New results after compression down abo0ut .5 and squish opened up .010"

    113hp / 119ftlb

    down about 6hp and 2 ftlb but a way different shape to the curve

    end result at the 5250 cross over there aint much difference although the torque carried a little further before.

    The big difference is in the engine temp is much lower now
