Replying to: jond09 (May 19, 2008 7:24 am) " But I guess all of this could be deferent do to the nature of the vehicle. But still a diesel is a diesel."   I just read a statement over on the F-150 MPG forum that Ford has programmed their black boxes to monitor the engine performance over time, and this would detect the fact that a chip has been installed, even if one pulls the chip before bringing it in for dealer service. If Ford has a way to discover that a chip has been used, they can void the engine and transmission warranty, i.e., refuse to fix them if they break.   I can't speak to the truth of the Ford "Black Box" capabilities, perhaps someone else has more details?

Replying to: stevedebi (May 29, 2008 11:02 am) This in a way could be true. Yes there are alot of vehicles that will hold in the computer if a chip/tuner etc.. has been installed even after it has been taken out. But legally a dealer can not refuse service/warranty unless they can show the chip was the direct cause of the problem at hand. Must of them will try to blow you off and tell you alot of things just so they will not have to fix/pay for the problem. Must even if the problem has nothing to do with the tuner,chip,programmer they will use this as an excuse not to warranty your vehicle. Replies to this message: stevedebi (May 30, 2008 12:09 pm)

"   But a chip affects the way the engine and transmission are run, so they could concievably have a case that the chip caused the damage.   But think further on this. To sue them you would have to admit in a public court of law that you modified the engine control chip - did you check with the EPA to ensure you did not illegally modify your engine? It could open up more problems than solutions.
#345 of 391 Need Help to decide by jim274 Jun 11, 2008 (2:43 pm)
I have a 2003 Chevy crew cab duramax which I pull a 33FT fifth wheel. I normally get approx. 11 to 12 MPG. I have installed a 4" exhaust with a low flow muffler and a K&M air system. ,Now I need help to find a cheap programmer and what is the best mode of operation? Should I pull in the #1 ecomony mode, #2 pulling mode for the best MPG? I dont need the other modes. Please help, Out of fuel in TN.

Replying to: dolphin1963 (Mar 04, 2008 8:29 am) I have a 2000 F250 7.3L 4x4 with a 6" lift and 35's, and get about 12mpg on a good day. I'm having a big problem with my fuel now that the price has gone almost to $5 in California. I would like to pick your brain to find out what you have done to get wuch good mileage. Having to drive from San Diego to Ventura, 380 miles round trip, is killing what little pay the military gives me. The good thing is I only drive that on the weekend. I would greatly appreciate any advice that you have. I also get funny looks when I'm driving 60-65 on the highway. Thanks again if you have any help.

Replying to: bigtexencorey (Jun 23, 2008 9:24 pm) Why do you want your truck to smoke? Most people on the road are going think something is wrong with it and Black Smoke doesn't equal more power, it equals over fueling which is really bad for your engine and your turbo. You see the black smoke is really unburned fuel which carrys a lot of heat through the engine and results in really high EGTs (Exhaust Gas Temps). Do you use your truck to tow any?
