Diesel Fuel Economy and chips



  • ktw1ktw1 Posts: 1
    Just got a 2004 3500 srw 4x4 quad cab shortbed that will be used for everyday transportation and to tow livestock. It came with a cool air intake, 4 in exhaust, gauges for (exhaust temp, boost, and transmission temp) and a quadzilla chip that has a dial for 4 positions.
    Was told the full counter clockwise position on the Quadzilla dial is stock set up. I am unsure when to use the chip and what position (1 thru 4) should be used for street or towing.
    Also would appreciate if someone knows the temps for the exhaust gas and transmission. Exhaust gas runs around 600 -900 when just cruising but can jump as high as 1100 or more when pulling a grade with a load. Transmission temps seem to stay around 180 unless under load the have risen to 200. I am trying to take it easy because I am unsure at what point I reach max temps.

    Taking delivery of this truck tomorrrow a.m. in Atlanta. It has 56K miles. What kind of mpg can (should) I anticipate?? If below mid teens, what is best fix?
  • hey i havea 2004 f250 diesel and i only smell antifreez in the cab when i get into the pedal or i have a load on and or going up steep grades any one know what it could be ?
  • about 8 to 10 around town and 14 or so on the high way if your lucky
  • My 99 diesel fuel lines are corroded and leaking at the front where they change from steel to rubber to steel...are there any problems with replacing the existing rubber hose that is about 1 ft long with a longer hose and double clamping each end? I want to do this to both the 3/8" line and the 5/16" line....about $12 vs $170.
  • I have heard only of a few things on the market that changes your mpg's so I am sure many of you know more than I know so I won't argue with any of you without knowing what I am talking about!! Anyway I have come across a product just a few months ago & tested it on my own car & my husbands 18 wheeler. On my car I have a 1998 Chevy Lumina over 200,000 miles on it. I got a baseline of 18mpg in town driving & 22mpg highway. So I started testing it while my car needed repairs on it (husband didn't want to change anything on it) It needed spark plugs, fuel filter, oil change, air filter etc. All of the normal things that needs to be cared for. So I used the product for 2 fill ups, first thing I noticed was increased horse power. Could pass cars without being scared!! Then I noticed that there was a decrease in mpgs down to 17-16mpg Then by the second tank it went up to 20mpg town & 24 highway. Then we changed the spark plugs etc & ran the car without any treatment in it for 2 tanks. Even with all the new spark plugs we dropped back down to where we were before & no horsepower again. So then I started using it again & we are now up to 21 in town & 26 highway. Oh & I also forgot to mention I have something wrong with the cadilliac(SP) converter. We are planning on replacing it. So I feel like it's worth it to have this product in my car. I can buy 4 packets for 17.95 & save about 80.00 a month because I fill up less. I dropped about 2 to 3 tanks a month. I was filling up 9 times & now I am down to 6 to 7 depending on the month. Then we got my husbands 18 wheeler no big detailed letter there, but he went from 4.8 to 6.1mpg loaded & 5.5 to 8mpg empty & increased horsepower. So there are products out there that does save on fuel.
  • What programer you running Cflowers?please share. dewey11
  • Took delivery and got 17~ back to Bham. But things got worse - 13 driving it to work via interstate. Then next tank did 15. Have seen as high as 18 on the computer...
    Will pull a 300 lb. pop-up camper in two weeks and see how it likes that...
  • I have a 06 F-350 4x4 w/3:73 rears. I always have gotten about the same miliaage with my truck, and did a lot of pulling with it. Empty on the highway I will get 20 mpg and pulling 12 to 15 mpg. I do seem to get better miliage using 04 fuel filters and they are cheaper. I don't have a chip or any after market exhaust, it's all factory. My truck runs 18" rims.
  • I'm looking for a shop manual, so I can work on my emissions. I can't afford a shop to work on it, when I can be a shade tree mechanic lol. Does any one have one they could scan and download to me for the emissions.
  • Their is a small radiator in the valley of the engine. This most likely has a crack in it. I had the same problem on my 2005 HD F-250. The smell only comes when the engine is under a load. The gas pedal being punched and sometimes up steep grades.

    I bought a Dr. Performance module for my Dodge. After 500 miles it stops working. It was replaced 3 times because Dr. Performance tested it and said they have problems with installation on some trucks and the module/chip burns out. Now they will not return my $450. it is bad again after 500 miles and say they are a new owner. Still use the same name and phone number. Do not deal with this Texas company.

    Has anyone run B99 in their daily commuter? I have an 08 Chevy 2500 and may have an opportunity to run it. Just curious about affects and potential for warranty voids.

    I recently bought a 1999 F250 supercrew 4x4 with the 7.3 engine that only has 90k miles. I was told and i have seen that many of these trucks get anywhere from 15 to 23 mpg on highway driving. I have a Bullydog triple dog programmer set to performance, which is the mid range tune, and all i am getting is about 12 mpg on 95% highway at 60 to 65 mph. I changed fuel filter, did not help. Truck runs fine, no leaks, surging, funny smell ect. Seems the truck got better mpg when it was in stock mode, but im invested in this chip. Anybody that has any advice please help, fuel is $4 bucks a gallon!!

    Hello fellow Powerstroker's

    Need a little help on this one, never had these Codes, lol. First Code 237 which says its Turbo Boost Sensor A Circuit Low Input - which one is Sensor A ? The other Code is 1316 which says its Injector Circuit / IDM Codes Detected. Now I am sure that the 2 Codes are tied in together and hopefully knows which is the Turbo Boost Sensor A is on the motor. Also if anyone knows what IDM stands for on the Code Reader ? lol

    Thank you very much in advance,
  • You should google b99 and read the article. You may want to sneak up on going from petrol diesel to bio. It can "clean" your old system and plug up filters. good luck and l would like to here how it works out

    IDM code = Injector Driver Module code probably.

  • Idrive a F350 Diesel superduty with a 39 ft flatbed trailer (7100) lbs with up to 12,000 lb cargo. considering a hypertec 111 to increase fuel economy and a little poewr boost. 350 has 116,000 miles. any advise.

  • Hey if you want know more about Diesel chip then visit this site : Diesel chip
  • My 05 crew is completely stock except for 33 inch tires and edge evolution cs programmer usually run level 1 or 2 and still mileage is around 10 to 12 on highway with no trailer. I ve chaged the fuel filter and air filter and switch over to amsoil. Any help would be great.

    My '96 7.3 has 190K on it. It got 18.5 mpg when I bought it 12 yrs ago. I put on a big exhaust, gauged it, Air Hog air intake, Amsoiled the engine, tranny and rear end, and chipped it with an Edge. It still gets 18.5. I have spent about 3K and haven't done anything except get frustrated.

    The advantage of the chip is when I tow my 29' travel trailer. Instead of the 11mpg it gets with the stock settings, it goes up to 13.5 to 14 with the 60 hp setting. But, you really have to watch the EGT and the tranny temp.

    I have never heard of a Powerstroke getting over 20 mpg, but have heard a lot of 12 -15 mpg claims. Anything you buy that doesn't live up to the claim, send it back.

    I had a 1999 Ford Diesel and always got over 20 mpg on the road. I also had an edge chip and it did nothing for the mileage. It did yield extra power to the underpowered 7.3. After 2 transmissions I now own a Chev diesel.
