i was told to NEVER NEVER EVER tow with o/d on EVER. an empty cargo trailer, 4 grown adults or 750 lbs in the bed is enough to demand to much on our trans. i have driven at 75 mph for 3 plus hours with a 2200lb camper without a problem.(except on gas$$)

 

I had a 3,400 lb loaded trailer behind my truck last week had od off all the time but did turn it on just to see how it would act needless to say hit od once and for about 10 sec then it kicked back down so I just left it off but I was really surprised that my truck really didnt have a problem with 3,400 lbs

 

I'm running a V6 so my truck doesn't have the towing power you V8 guys have.

 

only time i've turned mine off is when theres snow on the ground but don't need the 4wheel drive yet.

i tried turning it off today in town, but i forgot when i went on the highway. didn't really sound good at 90, don't think anything broke may be a little hot tho.

 

haha i did the same thing, sounds like the engine bogs down after 80 mph.

 

I believe the fuel pump switches off when u hit a certain redline. Not sure tho!

 

pretty sure thats if ur not running a superchips, where u have the speed limiter

 

**** i need to get me a superchips then lol. I wonder how much my gas mileage would improve. haha thats the only reason i want it

 

if you are on the economy tune and you drive like a grandma then you could pick up 2-4, is my guess.

 

which would be amazing lol. I get 13 driving like a gma as is. and im running a stock size tire as well. lol
