    Thanks for the info... I knew the extra cruising timing was related to the EGR, but never thought of turning of it's diagnostics.

    Engine has to reach a certain temp before it goes into closed loop. Even when starting a fully warmed up engine, it still takes a handful of seconds before it goes into closed loop.

    At least you know now... but it can take a couple full throttle pulls before it allows the throttle to open sooner.

    5FDP is pointing you in the right direction.

    The Peak Torque table when it's overshot it tends to close the throttle.
