Max fuel economy for the 6.5TD

[moondoggie]

Good Day!

Someone mentioned elsewhere, probably in the 6.2 version of this topic, that prechamber cups might help mpg. Experts?

1. Gears! My 95 pickup gained a pretty solid 2 mpg after I installed the Gear Vendors Aux. OD. You might want to look at an earlier post of mine. If the truck is 2WD (which by itself should help mpg), maybe it wouldn't be too far out of line for a max. mpg truck to go to a lighter 3.08 set of gears? Again, experts?
2. Is it possible that factory wastegate programming might be best? In other words, does spinning the turbo waste power, as long as there's adequate combustion air getting to the engine? I'm referring to the way our trucks pull boost over 1800 rpm under certain other conditions, which is anathema to making more power, & maybe even bad for exhaust gas temps.</font>

I can't WAIT to see where this goes.

Blessings!
