Diesel MPG Tuning

[Climer97007]

Anyone here ever done performance tuning for better diesel MPG?

What I have in mind is to tune the fuel lower, adjust the timing, and lower the boost, and see if there is a stable, safe, lower torque, lower HP, lower fuel, lower performance level that I can tune it to.

Then, my plan would be to hook up an Edge Juice or similar unit to tune it back to the stock level and to higher performance levels on-the-fly.

Has anyone ever tried such a setup?

Thanks, Gene
