2000 F-550 looking for best power/fuel economy.

Great info Rammertide', thanks!

What issues have you heard with the FASS system?

What I was thinking on the gauges was the tranny, boost, and EGT could move to the monitor, leaving room on the pillar for engine coolant, rear diff. temp, and gear vendors fluid temp?

EGR probe will be moved, it's just where it was installed on the truck when I got it. Exhaust shop just reinstalled it in same position on the new 4" downpipe.

I misquoted the pressure for the regulator, the how to I found listed 75 psi at X amount of shim thickness, shooting for 60 psi.

I'm on the fence about switching to single shots?
It's a work truck, and I think, fairly close to max gains on MPG?
There's only so much you can do with a 9,200# 4.88 geared truck...
Any general numbers on MPG improvments switching to single shots?

Thanks again!
