I found this site while trying to learn about chipping my 2004 F150. I am very old school and haven't worked on cars much since electronics took over. My disappointment in my trucks performance pulling a trailer is what started my interest. I was disappointed in the trucks performance in three ways: first the motor worked awefully hard (4000 rpm or more) going up even small hills; second it didn't shift as quickly as I thought it should when the hill ended and third the fuel consumption was terrible. I selected a trailer that was well below the advertised towing capacity so I think it should have been different. My son tells me I need to chip it (and more) but I don't want to make any mistakes since I love the truck in every other way. Thanks in advance - Jon
Welcome, glad to have you on board. I`m old skool too, electronics are not my thing so it`s great to have FTE for advice and help. I hope the chip helps but doesn`t affect your warranty if it still applies.
I run both a 2005 F350 SD diesel and a 1997 F250 HD 460.
Both are crew cabs, and I generally like them both.
The 250 has ~250K miles and was replaced with the 350 specifically for towing our 8K lb trailer. W/out the trailer the 250 gets ~12 mpg, BUT onlt ~5 with the trailer. The only way to generate HP is for the big 460 to increase its rpm from 2500 to 4000, and let watch the gas guage drop.
I have been reading a lot since posting and for the moment think I will start with the exhaust and see how much that helps. I will probably still ended up chipping it but I know better flow will help so it just makes sense to me to go with something I understand. I will keep reading though and watching any input from you all. Thanks again
One question. Have you taken your trailer to a scale to see what it really weighs. Our 30' trailer was listed at 6500 # but after the wife got done loading everything she really needed it weighed in at a whopping 9900#(she likes heavy dishes etc). This is why we went to the diesel.
I actually went down that road. I didn't take the trailer to a scale but I tried towing without any water in any of the tanks and basically no personal effects on board. Still the same experience.
It is possible the truck is doing fine and I am just not experienced enough (lived in Alaska where we boated not trailer camped) but I just don't like the motor having to work that hard for extended periods. A number of people tried to get me to buy a diesel but I had a bad experience with one many years ago and was trying to avoid a repeat performance (maybe not one of my better decisions).
