Well that's why. Lol

yep...never see 1200deg though, and I couldnt imagine pulling some of these loads with less pump. Over 100k of this abuse and still pulling hard, kinda worn out though. (just under 370k)

Would a freash up bring mpg up?

Should, when matched with new injectors, and timed right.

Hey guys what kinda mpg increase will I see with a turbo? I found a factory take off kit for 250 bucks complete kit only missing the engine harness to move the glow plug controller

When the aftermarket turbos came out they were advertizing 10-15% mileage increase. I didn't find a recent post, what are you getting now?

I'm getting about 15 mpg now if I drive like an old man if I run it hard or WOT to get up to speed all the time I'm seeing like 9-10 mpg that's with a maxed out fuel screw in the injection pump and no turbo

My apologies if this has already been suggested, but backing out the fuel screw and playing with the timing seems like your easy solution. If you are maxed out you are probably just making smoke from a lot of that extra fuel.

To be honest it smokes like a tuned PSD good bit of smoke but not too much lol. I would turn it back down some but then I would be sacrificing power bc I don't pull a lot but when I do it's heavy and I need all the power I can get. I would adjust the timing but I don't have the tools lol

Any smoke is wasted fuel period.
It'll help spool a turbo, but that's it.

It would go from 2.5" with a single glass pack to a 4" straight pipe

3 or 3.5 is really all you need.
Bigger can just create drone.
