Well, after almost two weeks, I finally received my JesseTune today and the first thing I noticed was a considerably smoother idle. Shifting is a bit more pronounced and the torque management is all but gone. My primary reason for getting the pcm tune was for gas mileage, so I'll update this when I get the new numbers. I think I'll send him my original pcm and have a balls-out runner made out of it.

The only thing I wish Jesse would do is send a print out of the mods he did that way if you need to send it back, you can give him more educated answers to his questions. It'll also give you an idea where your truck is.

Pretty impressed with the wake up he gave my truck so far and it hasn't tripped a code yet. :(

I got mine last week and installed it, I could feel a difference, but not what I was expecting. I do like the new tranny mapping, I spoke with Jesse and he is in the process of fixing me up with the "balls to the wall, beat the heck out of your truck" tune. I cannot wait to get it back! As customer service goes, Jesse is the bomb and I will order from him again!!!!!

I've not seen the gains he said I would in highway mileage. I did see a 1-1.5 mpg gain on city driving though. Better mileage on highway would be hard to do on my truck. I already average between 18.5-21.5 depending on the trip. Only got in the 20's on a trip across country and non-stop to a nascar race. This past weekend I did my normal mileage of 18.5 on a trip to cabelas.

I can never get that kind of mileage only maybe if I am driving between 60 and 65 mph. How fast do you drive when you get that kind of mileage?

I get that kind of mileage running 70-75mph and keeping my foot out of it and not running the cruise so that the truck doesn't shift as much. I back out of the gas sometimes to keep it from shifting. Also don't use gas that has ethanol. That kills your mileage. I have 3.73 gears in the truck also.

I can never get over 18 mpg going over 70, something with truck I guess. This is also with a gas tune from wester. I just put in some 89 octane with 10% ethanol and seems to be getting better mileage, so go figure.

I've had my tune for about 2 tankfuls and on the last tank

w/89 my avg was 16.7 (on the dic) mixed in town/highway

way better than the 14.5 I was getting pre-tune :(

Easier said than done here in California... :D

 

 

 

 

 

 

ya, and add 115* temps. and your mpg. go to sh*t real fast..

one of the things i found is take a good look at the frount of your truck. big square box, pushing all that air in frount of it. it's hard to get good mpg. with that.

i have a 03 SS and drive between 75-80 mph. and get 13.5-14.5 mpg. if i drive 55mph i can get 17.5-17.8 mpg. with the a/c on. so the best way is to slow down to get the mpg's out of our trucks, good tune up, proper psi. in the tires, clean air/ fuel filters regular oil change, and last drive like an old fart :driving:

 

as for me .....CAN'T DRIVE AT 55 ...i'll spend the extra at the pump :nopity:

 

:P

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.

      “It should be recognized, however, that there becomes a point where fuel economy oils do not make much economic sense for the end consumer—we talk about a fuel saving of ~€100 compared to a risk of €1000 Euros if the oil is too thin and causes increased engine wear rates. However, the benefit of these oils accrues to the car manufacturers. If their vehicles can save 1–2% fuel by using a special fuel economy lubricant, then that OEM can drastically reduce the amount of fines they need to pay.”   I liked this and the following paragraph as well but it’s really only touching the beginning of the benefits OEMs see from spec’ing these oils. After you factor in “out of warranty” service work and new car sales when these engines fail before their time, it’s a good racket for them. Just because you're paranoid doesn't mean they're not out to get you!
