Chips in TV.

[Danzman]

I have a Chevy 3/4 ton 4X4 with a 6.0 gas eng.
I have had no problems pulling my 12000 lb 5'r but my mileage is terrible. If I put a chip in would the additional HP help my mileage?

Generally speaking, you put a chip in to improve performance and/or power (which uses more fuel, not less). Most of the real-time programmers have multiple settings, one of which is an economy setting (which is maybe a little better than how the truck comes from the factory). But I have never seen one that is economy and tow at the same time.

You did not define what terrible mileage is but if you get more than 8 mpg pulling 12Klbs with a gas engine, you are doing better than average. If you are getting less than 6.5 then you might need to have it looked at. It could be the ECM but it could be a number of other things too.

I feel your pain,used to have a 2000 6.0 litre gasser and no matter what I did nothing helped. I put a chip in the ecm, had K&N filter, Tornado, Flow Master exhaust and no differance. My sollution was a Duramax, now instead of 6.5 miles per gallon I get 10.0 pulling 11,000lbs. Hope this helps.

Pulling an 11K 5th wheel with our previous Dodge 3500 dually with the 8.0L V-10 gasser, we got 8 MPG. When we moved up to a 13.5K (and taller) 5th wheel, mileage dropped to 6.5 MPG. Is your mileage somewhere in this range?

OK. Thanks for all the replies. I do get 8.1 mpg so I guess I should be happy. Mainly the 26 gal tank is the problem so I guess thats what I'll have to replace or add to. Found a replacement in Ca but $965 is too steep. Thanks again for saving me the price of a chip.

I think you are about 2K pound over loaded if not more. So 8.1 is not bad.

transfer flow makes a 45 gallon stock replacment tank that just over 700. I built a tank out of sheet diamond tread thats 1x1x4' it holds about 26 gallons , I just pump into the filler neck while i drive. I drilled a tap into the filler neck and have a 1/4" fuel line and a small electric pump to transfer the diesel. This may not work with a gas motor due to closed tank venting ????? that would mean that you would need a check valve / solinoid and a pump

In general, putting a chip in a gas engine will not help gas mileage any measurable amount. I think you are working the devil out of engine with the trailer you have. Usually a chip on a gasser will mean you need to go to premium fuel to avoid pre-detonation or knocking.

As a point of reference, my diesel gets 10 to 11 MPG with my 4.10 axle and running 65 to 70 mph.

Small block gassers just were not designed to work so hard. Basically to get the HP out you have to put the energy source in to the engine in the form of fuel. Once you go to an overload state, the fuel consumption will go up.

The chips for gas engines don't accomplish near the gains they do on diesel engines. Many boast of milage gains but have never heard of it actually happening. I wouldn't waist my money at 8 mpg you are doing about as good as it gets.

Danzman,

Sorry you keep getting bad news, but that small block is working its guts out to pull 12k. You need a 8.1L at least, and if you tow a lot, a turbo diesel.

Don't waste any more money on your current truck, if you keep pulling 12k with it, it won't last too long and you can upgrade. Save your money for the upgrade.

I started out towing with big block and hated the fuel ecconomy, I then tried a small block thinking that a little less power would = better ecconomy. Boy was I wrong, towing with the small block, I was working it so hard I got just about half the ecconomy of my big block and still only had half the power.
You want to tow big weight, you got to have big power.

Remember, there's more to life that gas mileage!!!!
