start up of a 2001 F350 7.3L in -22C weather (about -8F in the USA) the truck has a 4 inch turbo back exhaust (right from the turbo back) and a stage 2/3 AFE intake. This was a cold day and if plugged in they start up pretty good just more exhaust until it warms up.
mines a 02 7.3, stage 2 injectors, 5 inch dp to 5 inch straight pipe, napa 6637 intake with the wicked wheel, dp tuner, 8 inch lift on 40's and i get about 8 mpg :( i used to get about 18 with stage 1 injectors but i guess thats the downfall to having more power is less mpg. and yes it is possible, you can google 40mpg 7.3. diesels are awesome and can do just about anything when tweaked just right.

@MattFoster10 keyword 00' f350, they are pigs on gas compared to a inline 6 cummins. I know because Ive owned both. Ive also got a 5" turbo back exhaust (straight no mufflers) a banks high ram intake manifold, afe stage 3 intake, and its a 6 spd truck reg. cab. I can net 26mpg on fuel eff.

@tksemipro you have completely underestimated the capabilities of a diesel engine.

@longboardguy Is that according to the lie-o-meter in the truck?
