    color change...photoshop request.

    There is a which gmc around here that has the top of the cab, including the hood black with the lower body at the bed rail white. It looks really sharp with the dark windows.

    Eco tunes for unladen long distance highway mpg's

    Oh for sure. I get the mileage difference between the 2 engines but guessing the hot tune theory is the same.

    Eco tunes for unladen long distance highway mpg's

    What do you mean? I can see 30 on there too?? LOL If you are cruising highways, you should be locked up and making minimal boost. The best results I have found is my hottest tune. My extreme x from Eric will get me 18-18.5, hand calc, doing 75. Just go easy on the on ramps. This is with my 6.0...

    Transmission mount

    I've bought a lot of stuff from autonation, formerly Tousley ford. They are local to me and have great prices. Be sure to mention internet pricing if you call.

    What would cause this?

    I have seen sidewalks bulge like that but not the bead. Looks like the cords were broken when mounting. It makes me curious as it is on the inside of the wheel. You should be able to jump that truck with 37's let alone hit a curb.

    After a day of cool down, compare the ECT and EOT temp readings. If they are the same, sensors are good. Before checking your TD, be sure the truck is good and warmed up and you are driving easy, flat road at 60mph.

    Revs/mile and speedo correction

    Mine defaults as well. I have my revs written on the back of it. I don't see what would matter as long as you speedo is correct which is then keeping your odometer correct. Then the truck will know how fast it is going to make the proper shifts. I can't tell you how it works bit I think that's...

    Revs/mile and speedo correction

    Don't get so stuck on your actual tire size. If your speedo is reading lower than your actual speed, decrease your revs per mile or vise versa until you get it right on according to the gps.
