    How much soot should be visible when accelerating through the gears and then cruising at highway speeds

    Thanks

    A slight puff between gears is normal. Cruising at highway speeds you shouldn't see any on flat ground, as you increase the fuel to compensate for a hill you will probably see a slight puff also.

    Little or none if running right. Might see some on hard pull.

    What could be the problem if there seems to be more than a puff

    Is it continuous when under a load or only when shifting through the gears and throttling up for a couple of seconds?

    '03, that was before all the emission BS right? So you have no DPF (diesel particulate filter) on there?
