pump timing
 

Will advancing pump timing increase mpgs.

exhaust temp decreases
cylinder pressure increases
intake manifold decreases
bsfc decreases
nox increases
heat rejection decreases
hydrocarbons decrease
black smoke at 1000rpms decreases
black smoke at peak torque increases
black smoke rated decreases
white smoke < 1000rpms decreases

not to steal a thread or what ever but i was just about to make a thread about this, i did the timing on my old 89 cummins with ve pump, and i did it 1/8 of an inch, everywhere i read about p pump its like 13 to 18 degrees, cant i just bump the mark 1/8 just like old style pump?

uh... kinda you can mark the balancer but we are talking thousands of an inch so advancing the timing by an 1/8th of an inch at a time is pretty inaccurate.
