1988 Mitsubishi Fuso FH Turbo, 6.6L diesel, anyone have some proven mechanical tips or tricks to improve fuel economy? Thanks, Cliff

What trans and final drive ratio? Does it have overdrive? On a rig like that it's all about gearing. And it's hard to make a brick aerodynamic. IMO

I would think that money would be better spent on aerodynamics than on the engine. The best fuel saver for the engine is your right foot. If its a box truck a nosecone may help.

There is no dpf, but have you gutted the kitty?
I don't know of a bigger pipe is available, you could always have one welded up.
Still, it's a small engine in a large brick.
