You need to rethink this post. I thought it looked "suspect" and when you said it is a 6.0 with 4R100 transmission, I knew it was flawed. This combination was never available. The Torqueshift transmission was the only one available with the 6.0. The 4R100 was with 7.3 diesel. What combination do you have?

 

That's impressive....I can't imagine what you get going downhill....

 

He's joking or trolling guys lighten up. He's posted the exact same thing in the Excursion section. Brand new user account registered today with 2 identical posts? Pfffft. Lol.

 

Yea I noticed....I was being sarcastic.

 

Wasn't directed at you so much M-P, my bad should've clarified. That and I just noticed my phone corrected it to guys indicating both of y'all. For a smart phone this thing is remarkably stupid.

 

07 f350 3.5" down pipe, 5" exhaust, sct trans tune, banks six gun (on highest level all the time), 325/65/18 duratracs (@55psi), 3.5 ready lift kit, colt stage 2 cam, bd manifolds. On the highway can pull 20mpg easy, around town well lets just say I got a heavy foot.

 

Can you tell us alittle about the Colt camshaft? Not a common mod around here and was wondering if there are anysignificant gains to be made with an aftermarket cam..

 

Rusty, I can honestly say yes it made a difference. It has a very smooth pull when say passing on the highway. The turbo seams to come in earlier also. Power wise, it pulls harder than it did with the stock cam. On a hard accel the front of the truck seams to get more lift and pushes you into the seat with authority. I can also say the wheels break loose with very little effort. I would recommend this cam to anyone that needs to go that far into engine. The fact that it was a straight drop in, other than the addition of the high rev springs I added, really appealed to me. Now I cant say my mileage improved much but the truck is a hell of a lot easier to drive. I spoke with Geoff on the phone before I pulled the trigger on this. What really sold me was what he found on the stock cams that could be the reason lifters go out so often on 6.0 and 6.4. I needed to reseal my engine and being I was right there it made sense to me to change it out. I do work for Ford and change quite a few engines for lifter failure which oddly enuff are the same ones in 7.3s IF memory serves correctly. And really how many have them ever broke? I would strongly suggest calling them up and asking them any questions you might have as they can answer them best. I am trying to get on my co-workers dyno, to try to get some real numbers, but his work load is kinda high right now. I posted the cam card so you can compare the numbers yourself. I went with stage 2 cause of the fact it is a new grinding with a stock base circle.

Nice to know it responded well to a fairly significant increase in exhaust lift and duration. I assume this moved the power band up the rpm range a bit but it's still pulling hard on the low end. I've messed with this a bit on gasoline engines but how it would affect a diesel is a mystery to me. Thanks for the info! Reps.

Sorry for the

 

My 06 6,0 has 4.5" lift 33 12.5 tires. 4" turbo back exhaust SCT tuner custom tunes from gearhead.
Here's a few runs over the summer. The 16 mpg was on the hwy with just my sxs rack in the bed 350# the lowest ones were with my rzr on the truck and a 3500# 24' camper. And I get around 1pg just around tow. But I have a heavy foot

 

Thank you TennesseePowerstroke. I was wrong about what kind of transmission is in my Excursion. It's the 5R110W transmission. Yes, I'm new here.

 

Thanks for the clarifitcation. The guys on this forum are very helpful and will be glad to help with any questions you have. Welcome to the forum.

 

Here's my experience....

Towed commercially delivering RV trailers for about 3 years: towing travel trailers, about 9-10mpg, 5th wheels about 10-11mpg, not towing about 20mpg as long as I set the cruise control to 60-62mph.

My valuable lesson... when towing in cold weather, never let the main tank get below 1/4 before you transfer fuel from the auxiliary tank your truck bed into your main tank - it may be too cold for the pump! One cold morning on the way to Fargo, ND, my main tank was low and the aux tank was full - about 50 gallons. But it was cold enough that I could not get the fuel transferred via the electric transfer pump (a bit like a someone on a raft in the ocean with no drinking water). I kept dropping my speed and watching the miles til empty. I was lucky and made it to the truck stop to fuel up, but from that day on when the main tank drops to 3/4 tank, I transfer fuel from my aux tank to top off the main tank.

 

2007 F250 4X4 with Banks power system and Monster exhaust..........getting 13 mpg around town in "stock" mode.

(same as I got with my previous 2000 F250 7.3L two wheel dr.)

 

Check my Sig, 17-18mpg's with my setup @ 55-58mph, unloaded.

I am usually the guy that everyone cusses out for driving so slow, but at least I stay in the right hand lane.
