I agree the 20's really help the looks of these larger trucks. In my case larger tires and wheels were worth my lose in mpg. If your planning on getting a chip/programmer I would just leave the wheels on. You should gain back 3-4 mpg with the write one with your intake and exhaust. As far a warranty goes you have to remember that no dealer or mechanic likes to do warranty work. The dealer doesn't make money and the mechanics get paid half there normal hours, so there going to be looking for a way out of warranty work. But legally they have to warranty your truck unless your aftermarket accesary was a direct cause of your issue. They cannot just tell you they want warranty any problem because you have a programmer. Chip or programmer I would serouisly consider getting one that has a read out of all your temps or invest in a set of gauges. This will help keep you from killing your motor or tranny. I don't know if you got exhaust or you just took off your cat but I would get rid of your factory muffler too and get a straight through design if you haven't already. This will help lower egts further.

I saw on one forum on another site that adding pure acetone to the fuel at a rate of 2oz per 10 gallons increased the mpg by 3-5. Anyone else have input on this? It actually had a video. I'll try and find it again and post the website on here.

I'll definitely get a pyrometer and tranny temp gauge if I go with a chip. Problem with removing the muffler is that I'm not a fan of the louder sound. I've also talked with guys who said they get a drone as well? Is there a muffler available which increases air flow but doesn't sound like the beast has been unleashed?lol I like the sleeper type of truck. I love that when I stop at a light and a tuner pulls up next to me that I beat it off the line! And I'm driving a one ton!lol And no cloud of black smoke or loud noises show it's a stock truck. At the second light I usually get a look of disbelief!lol I've never had a chipped diesel and can't imagine how it must feel when my stock truck already impresses the hell outta me! I just had the cat removed as it already has a stock 4" all the way from the turbo.

I agree the stock 4" exhaust is pretty good. I just remove my cat as well and put a magneflow muffler in place of the stock one. I think it sounds good, not to loud at all for me. It really didn't get much louder, just a better sound. Got it of ebay for $75. The stock muffler is very heavy and veeeerrrryyy restrictive. If your impressed with your truck now, you won't believe it when you get a chip. I also love messing with the tuner cars. They really fell bad then since I'm running 38" tires and I can still smoke'em.

The magnaflow sounds like a good choice. My first real deal with a chipped diesel amazed the heck outta me! I had a gs1150 motorcycle 172hp. This thing would go. I pulled out to pass a dodge pickup on a 4 lane one day and he stomped it as I was going by. I was in disbelief that the acceleration was so fast! We hung side by side up till 112mph then I cracked it and got away! Then I went and bought me a dodge diesel and am on number 2 now!lol Have you heard of the workhorse module? Everything I've read makes me think it would be a good choice.

Fifth Wheel Pulling Mileage

I own a 2004 Crew Cab 4x4 with the LLY motor. It has 75,000 miles on it and it is still stock. In the summer on the level with minimum stopping at 60 mph I can get 20 mpg. I am looking at purchasing a fifth wheel RV with the weight of between 8000 and 9000 lbs. Can anyone tell me about how much my mileage will drop. I know that the faster I travel over 60 the more it drops without a tow vehicle. I only get about 16 at best at 70 mph. I have thought about installing a Bully Dog and am also interested in anyone who has experience with them and how much it improved their mileage.
Thank You
John

Since you report the odo reading in kilometers (km) I assume that you are in Canada. So the 27 mpg is 27mpgC = 27 / 1.2 = 22.5 mpgUS. Right? Of course this is still very good for a 3/4 ton truck.
Isn't fuel in Canada sold by the liter (L)? And do the odometers in Canada read in km only? So you convert L to galC and distance in km to mi. Right?
Do Canadians usually report fuel use in liters consumed per 100 km driven (L/100km)? Could you give some raw data and show how you do your calculations to get mpgCanadian?

I have a 2008 F250 6.4L Diesel with the 20"wheels and about 4000mile to date and my day to day average fuel mileage is about 11.8mpg. I drive about 60% highway / 40% city. I've read many that say their mileage is the same as mine but then there are those that are getting much better. I will have to say that it is hard to believe after driving mine. I read that the 3rd build cycle will be installing 3:55 and a taller front air damn.... http://www.pickuptruck.com/html/news/ford/superduty/jobthree/jan08change.html
My F250 is having a multi check engine light problems that have no fix available at this time so Im looking into Lemon Law but I will be looking into replacing it with another just like I already have.
