I would like to get a bit more response off idle and clean up the light blue smoke at idle and when initially accelerating.The 22* is only if you can rev up past 3k. On a regular 8.3, I wouldnt go over 3-4* of advance, and 16 is decent. Most of what I mess with is a DT466, which is a very similar setup as these(almost identical pumps). The low end torque really suffers with timing of 20 or higher. On the flip side, the trans will like it a little better with the torque a little higher in the rpm band. For normal driving, if you play with the timing, you'll find it will probably only want 1-1.5*....sometimes not even that much. It's all in how you like it.
I have installed the pacbrake gov spring kit and turned the top screw out 3 turns and its a pleasure to drive now and doesn't make me nervous pulling into traffic.
Can I loosen the pump and turn it a bit or is it like the 5.9 and we have to pull the gear and reseat the gear?
I'm not big on black smoke for power(Truck gets enough attention without that) so I would like to stay within the black cloud realm and get the most out of the fuel.
