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!

I'll post a lnk bellow to give you some other ideas. I've had gauges on the pillar for 2yrs. While it looks cool, it makes bit of a blind spot and scratched the hell out of my dash anytime I had to take it on/off. I now have one gauge on the steering column that can read everything via OBD2 port and auxillary sensors. I'll post links to that as well.

It does use less oil pressure since it is only firing the injectors once. I've also read that it is easier for tuners to tune since it is 1 shot of fuel and not 2. Split shots were meant to be emissions control. I don't know of anything that was put on diesels for emissions have helped them with power or fuel economy.

Thanks again!

Using RiffRaff you have to send him your cup holder so he can match the paint. This link below, you can buy the piece and paint it yourself. An automotive paint store can match and make the color paint for you to paint it yourself...

The F-650 swap is sweet, adding that to my "list".
