I don't really like the shift points on the Edge chip and have had good friends tell me to get rid of it but I don't have the $ right now. Plus I have nothing to compare it to so it does the trick

I guess I will take it to a stealership or a shop that can test all of my sensors. Not helping my cause is that city driving here is chock full of hills and lights. To work and back is all the city driving I do tho
one year old brakes in the rust belt does not mean anything.
make sure they are freewheeling. i had a brand new from the dealer caliper lock up on me 2 months ago.

Too true!!! I had to replace a rear seized caliper 3 weeks ago. I just figured it was a bad caliper I bought. I'll give them all a check. Thanks

another thought. are you using the lie o meter for mileage, or hand calculating? because the lie o meter will be wrong with a chip or tuner.
and get rid of that edge and put a chip with custom tunes in the truck, you will be much happier with the way it runs.
I hand calculate it. I'm reluctant to get a new chip because this one has gauges already so to replace it I would need to buy a chip and gauges. However I'm thinking about it. Any suggestions on which one?

Hand-calculated based on erroneous data from the odo with bigger tires. I won't say you'll double your economy with the ABS adjusted for tire size, but it's not quite as bad as you suspect. Even with the tire adjustment, city traffic, hills, and short drives kill economy on a 3500 Kg diesel. If you're near Vancouver - you're doomed.

You may want to try a grill cover; especially given your frequent short trips. It really helps the engine warm up quicker, and stay up to operating temperature in low-load conditions, in which the motor would quickly cool down too much. They do also provide some aerodynamic benefits as well, but that is mainly at highway speeds.

i would never run a grill cover. at 10 degrees my engine only takes 4-5 minutes to get to 190 degrees, and stays there even at 65 mph on the highway.

I find it very hard to believe that you are able to get the motor up to 190 deg with only 4-5 min of idle, even at a fast idle, even with the EBPV; and at 10 deg outside air temps.
In any case, 190 deg is too cold for optimal combustion in these motors. Even little 4cyl gas motors run hotter then that, for efficiency (generally 205-210 deg operating temps).
At 190, you aren't even opening the stock Ford t-stat, let alone the hotter IH one many people switch to. Its not good to drive around with a "permanently" closed t-stat. With restricted coolant flow, you will have various "hot spots" in the motor that aren't getting proper cooling.

I've had mine on for a few weeks. Temperatures have ranged from in the teens, up to mid 40's for a few days. During that time, I've done high speed highway driving, in town "normal", and in-town "crawling in traffic for an hour +". I've done this empty, as well as with 4,000LBS in the bed. I've run in stock, daily driver, and the tow tune. I've gone easy on it, and I've driven it like I stole it. The dash temp gauge has never climbed higher then half way, which is where it pretty much stays at no matter what, only slightly cooling off with either extended idle or extended highway running.

I actually made my own last year, out of cardboard covered in clear packing tape. It looked pretty ghetto, but it worked. It only started to fall apart as spring started, since it was then exposed to a lot more liquid water, instead of just snow/ice/slush that quickly refroze. Again, I had no overheat issues last year either. Even with the cover on, tons of air still gets through, via the gap between the grill and bumper, as well as the opening in the bumper.

As I also mentioned, grill blocks can offer aerodynamic improvements, by reducing drag, and even improving handling at highway speeds.

The inside of your engine compartment is basically a big square parachute. Air gets shoved in faster then it can get back out, and creates a positive pressure. First, this causes drag, reducing fuel economy. Second, that trapped air/pressure pushes up on the hood, and anywhere else it can, and causes a small amount of lift. While you aren't going to need to contact the tower for takeoff clearance, it can be enough lift to cause the front tires/steering to feel "light" and "darty". Turbulence from heavy wind gusts and/or passing tractor trailers can amplify the effect.

By blocking the grill off, you can substantially reduce the amount of air getting packed into the engine compartment. Anything you do in this area will help. If you can block enough of the air, without causing the vehicle to overheat, you might even be able to create an area of negative pressure under the hood, resulting in "down force". This will make the front end feel more "planted", and improve highway stability. Granted, too much down force can increase drag and reduce fuel economy, but I doubt you would be able to (or want to) seal the Super Duty engine compartment enough to worry about that.

Also, several of the major auto manufacturers (Ford, Dodge, various GM divisions) are now including adjustable, computer controlled grill block offs, commonly called grill "shutters" on several car and truck models.

4or 5 minutes of driving, not idling.
and after 5 minutes i have to open the window because it is too damn hot in the cab.
same with my 88 diesel.
the crown vic on the other hand takes 10 minutes of driving to get any heat.

Wow, at that temp I peak out at about 165 degrees unless I put a large load on the truck - for example back to back WOT tests.

Actually... I want to get my transmission over 130 degrees. As for the EOT - I have no problem frying my toes right-the-hell off. They call me "Smoldering Sneakers".

I just swapped my stat with a new OEM. It was 17 this morning, block heater was plugged in on a timer (3hrs) and idled for 15 min before leaving. Heater was cooking my feet. Prior to that, it took 3 miles to heat up with constant EBPV and the associated power loss after same idle time. Now, I am of the opinion, if you can't achieve similar results, suspect your stat....without a grill cover. However, I do want to get one...

I would do a leak test to see if you have a leaking boot somewhere. i get 12 to 14 towing my 8500 lbs+ toyhauler full and anywhere from 16 to 19 highway empty
with my 4x4, 4door, auto.

It's much worse than Vancouver, I lI've and work in North Vancouver! A city basically built on the side if a mountain. Lol
