They said I have to take it in so they can hook it up and reconfigure it my gas mileage sucks now 12-13 empty city hopefully this will improve maybe your truck is on this recall too

Replying to: akseagirl (Jan 23, 2006 3:08 pm) YES, I still love my Dodge Diesel. After adding the Quad.chip and boosting HP to almost 400HP, it is like driving a high performance sports car. My gas mileage has remained 2 to 4 MPG above stock. However, after driving a 2001 standard 6 speed the other night, I am wondering if I was towing up and down hills if I would not consider a standard transmission next time. I was extremely impressed by the 6 speed transmission! I was pulling a 32 foot goose next and I never even knew it was behind me. So, I guess my recommendation (even though I love my auto) you may consider a standard transmission for towing up and down mountains.

Replying to: deiselden (Jan 10, 2006 7:32 am) WHY are the '04 4x4's so low?? I have one...and have been disappointed in the economy from day 1. (This is my 2nd Cummins. I average 12-14mpg, when I'm towing on hwy, I got 10-12 at 72mph. I can eke out a little better when I drive like Grandma, and keep the cruise on 55. 17 is the best I've ever done. My truck has 45,000 miles on it, larger tires, and I keep the fuel filter changed religiously. I put a Bullydog on it and while it absolutely smoked, my leadfoot didn't help the economy ...it actually went down! So I didn't buy the bullydog. Should I try another chip? What can I do? I love everything else about my truck...surely there's something I can do. The dealer says nothing's wrong, but admits it should do better. Thanks for any advice...

Replying to: manyskilz (Jan 25, 2006 6:04 am) I am not sure if it is just the 04 model or more to do with 4x4? I would suggest adding locking hubs to your truck. I have been told by several reliable sources that this will increase your mileage by 2 to 3 MPG. I have recieved better mileage with my Quadzilla vs. factory (2-4MPG better, if you can keep your foot out of it). I actually stated 5 to 6 MPG better in my first post about my Quadzilla. What I found was that the chip interferes with the digital mileage meter. Once I actually put it on paper it was around 2MPG pulling trailers. It definetly seems to help my MPG.

Replying to: ezshift5 (Jan 27, 2006 8:29 am) A 4x2 2500 regular cab with 3.73s will indeed break 25 mpg on the highway. My 3500 4x4 Quad Cab dually will see 21 if I baby it.   kcram - Pickups Host
#122 of 391 chip vs programmer. What is advantage of each? by capps Jan 29, 2006 (10:57 am)
I recently bought a 2000 2500 4X4 quad cab long bed diesel auto and this is my first diesel. A friend installed the edge ez in his ford diesel and loves it. So I started to do some research and have seen chips and programmers use and wondering their advantage. I have a 25" toy hauler trailer I will be pulling loaded about 8000 lbs. I would like a little more power and better gas mileage is always a good thing. Any info for a new be would be help. Thanks!!

Replying to: ezshift5 (Jan 27, 2006 8:29 am) Yes, I do believe Cummins is capable of getting 25MPG. I have friends that constantly get 24 MPG, mostly highway driving with some city. Personaly I keep my foot in it way to much. I usually average between 18-19 MPG, pulling a trailer mixed with highway and city driving (loaded/unloaded,no trailer,with trailer) Another words, I have not ran a full tank without mixing pulling into the equation. If I strap a loaded trailer on and run until empty, I will probably average 16 MPG (12-14 before the chip). --I had a hard time believing this also. After seeing my truck break in and watching the numbers, I do see where these trucks can hit the 25 mark.-- Replies to this message: ezshift5 (Jan 30, 2006 7:20 am) sirradiodude (Dec 02, 2006 1:02 pm)
