Towing power / Programer by banshee409

Has anyone tried a programer for a 2004 1500 chevy? I am currently towing a 20' V-nose enclosed trailer with my truck and it's a load. I have taller tiers so I believe my 373 are at about 361 compared to the stock tires. How about after market exhuast and a K&N filter also? Are these kind of things worth it or will I be wasting my money? I have a hard time keeping the truck in overdrive even on the flats with little wind.

Forget the programmer you can use tow/haul mode. Forget the exhaust and filter as you will lose power on the lowend which you don't want. Swapping gears from 373 to 411 will definitely help power wise but not mileage which is probably suffering anyway.
 
The power band of the 5.3 is up in the 3-4K range which doesn't help when towing in OD but I think you know that already.
 
Consider the 411 probably your best bet and it doesn't make that much of a difference in gas.

brake controller install by cubpilot

I just wired my brake controller on my 07 Silverado NBS. I know it is wired correctly because everything functions as it should. Only problem is after i finished, i manually applied the brake on the controller, and it sounded like my fuel pump began to run, and my compass on my mirror came on. I started the truck, applied the manual lever, and didnt see anything abnormal, shut the truck off, did it again, and nothing hapened the second time. Has anyone heard of this. I have the wires hooked up correctly under the hood, and could use some help. Thanks!

Duramax or 6L that is the Question? by ritchiec
Aug 09, 2008 (8:05 am)

I am looking to new or used 2500 hd. I know that the duramax is a pulling machine, I had one of the first ones and the latest was a 2005, but I don't work for that company anymore, So my question is with diesel as much as 50 to 70 cents higher depending on the time of year. What kind of fuel mileage does the 6L with 6 speed auto get pulling say 12000 lbs which it says it can do. I know the duramax will out pull it with ease, but to suffer the performance is it worth the cost of fuel and the $7000 difference in price. Any comments

Trailer brakes only work when manually applied by jschroer

I have a 2006 duramax and about a week ago I pulled my fifth wheel trailer for the first time this summer, and I think I blew a fuse or a relay because before I pulled it the trailer brakes worked fine but after they will only work when I squeeze the controller but not when I apply with the pedal. Where would I find the fuse that controls this? I have looked at the fuse blocks but can't seem to locate it.

My 8.1 gets about the same mileage as a friends 6.0. And when towing, that 6.0 works alot harder than mine. If you're doing a lot of towing, go for the Duramax.

I believe GM feels that 3 low batteries charging at once could overheat the alternator. 2 in truck, 1 or more in trailer. 2005 owners manual says not to put in 40 amp fuse if you have diesel (2 batt) or an aux batt in truck (2 batt).
    If you have 3 low batteries, lights on, a/c on hi, etc that's too much load. Leave lights off, fan off, charge truck batteries 10 min. then plug in trailer after dry camping.
     If your truck batteries are at full charge then no problem.. we put the 40 amp in an 05 today.

Tow and haul by cprovost

Why when I put the tow and haul on when I pull something it is winding out. I brought it in and they said they could not find nothen rong. A nother problum is my rear tires are locking up but not all the time. If I take off and at the same time I hit a bump are if the tire spins a little bit it starts to lock up. A nother problum that GMC said there was nothen rong. Its a 2006 GMC crew cab
