My towing question...
Newbie here, after reading couple of posts thought I might get some insight to my truck prob. I have a 04 4X4, 6.0. with 65000 miles on her. The guy who owned it before me had some kind of chip in it and blew out the top end. The local dealer fixed the motor, and took chip out.
I bought it and recently tried to tow a 7000 lb camper. It has same symptoms as others have posted....no power going up any kind of hill, won't go over 65 mph, and MPG has dropped from 16 highway to 7.9. Bad thing is I dont have any gauges on it, so cant tell what engine is doing.
Where do I beging troubleshooting this? Is the 6.0 just underpowered for that much weight? It is supposed to be able to pull 12,500. What would be a good chip to put in it? And lastly, do you need an intake, exhaust at same time you add a chip?
Thank you in advance for any help and opinions......
