    i was thinking of the readings KPA/PSI per cyl .
    Anyway after checking it out as a dry test was 180PSI per cyl
    So that seems promising for future mods yay

    All good after talking to afew guys on the ls1tech site , 180psi per cyl is normal for a stock motor but gonna get the leak down test on it soon to make sure piston rings stay good as i only need to check up on the bottom end
