    Looking at this Dyno chart, where would you say the best gear shift up point is being a diesel? On my race bikes I would set it just before max BHP to allow for the delay in changing gear and the revs still rising while doing so, not sure what's best being a diesel virgin. Would you use the Max Torque or the BHP?

    For normal driving probably around 2000 RPM, for pulling loads around 3000-3500 RPM.

    For a quick sprint .. depends how many revs are dropped by gearing up, lets say it's 1200 revs I'd change around 3500 (as torque has started to drop off), that would drop you back onto the around 2400rpm where the torque is right back up there. Its the torque that gets you shifting.

    Cheers @SpeedyGee :Thumbup:
    Not too far off what I'm doing now then, always used to reving engines being petrol but liking this diesel malarkey.
