Question about 2004 Dodge Ram 1500

1 Answer

I want better gas mileage.

I have heard there exists a computer chip/card that can be installed to boost gas mileage by recalculating the fuel/air mixture that is injected into the intake. Is this true? If so, where can I purchase one? Can I install it myself, or should I take it to my local mechanic? Do you think it is worth the expense?

Thanks for responding.

    From what I understand, there are different chips for different requirements such as, more horsepower, better gas mileage, better torque,(pulling power) etc. and maybe one chip that promises to do all of that in one. That said, if this chip can only do what it says it can, providing I allow it to breath better, which would mean a higher priced air filter assy like a K&N, then it needs better exhaust flow, well lets install an exhaust system that will allow it to flow out better, by the time I have all that done, and figure out how many gallons or liters of gas that would have paid for, is it worth it, because if I decide to sell this vehicle later, or trade it in, all that money I paid out for all that stuff, isn't going to matter much to the average guy or the dealer, it's still a 2004 Ram, or Ford Or whatever, and this is what the black book says it's worth. It's like trying to get more for your vehicle because you had to put a rebuilt or used motor in it recently. The going price doesn't care what you spent on it, only what the rest of them like yours is selling for, unless you happen to get that one in a million guy who it does matter to. Better gas mileage can be as simple as a rear end gear change, but if that change means you can't make it up a hill now, was it worth it? If the chip is going to advance my timing, more than recommended by the maker of the vehicle, then I worry about what that is doing to my engine. Air & fuel mixture is monitored now by your sensors & engine computer, and adjusted as needed automatically. I suspect the manufacturer has set that up to run at optimum performance & mileage already for that engine to last. If you watch auto racing at all, it isn't uncommon to see a car pulling into the pits with smoke running out the tailpipe, done for the day, because they leaned out the mixture a little too much trying to get better gas mileage, which obviously heated up an engine part past it's threshold. Basically all the adjustments they change always makes me wonder what is really going on inside that engine, and why didn't the manufacturer make it that way, especially when they always advertise more horsepower than, or more torque than, or better mileage than their competitors. I'm guessing because it will wear out the engine prematurely, but how can you prove it ? I will say this much, that when a lot of the Big gas powered motorhome owners tried for better mileage at the dealerships where i've worked, most spent their money on bigger, better flow exhaust systems, and a better air filter system first. More air in & out usually is a good place to start, but you have to deal with somebody that knows their stuff, not just any exhaust place. If they are knowledgable with the "banks" exhaust system and perhaps "K&N filter system, then take the time to hear them out, and decide from there whether it's all worth it. If I have to spend $2000 in the end to get the results, but I travel a lot, and plan on keeping the truck for a few more years, then maybe it's worth it. Does the fine print for the chip say "results may vary" for any reason? Because if it does, my guess is, it varies according to what else you do to help it. If you want 10% better mileage, drive a little slower, coast a little more, accelerate a little easier & gradual, keep tires up to max, change oil when required, change air filter every spring and fall, and you know the rest of that tune. If i was planning on racing the truck then I'd probably grasp at anything to give me 1% better performance, or just watch what all the winners are using, and get one. Well that's my 2 cents worth, hope I didn't bore you.

It's True. On my diesel it makes about a 3 miles/gal. difference. It probably wouldn't be as much on a gas. Maybe about 1 or two mpg if you take it easy, but you will love the power increase (up to 30hp+), which will make it hard to take it easy. It will also give you firmer shifts. You can get programmers/chips on EBAY or possibly at a local performance shop. The programmers just plug under the dash and once the desired program is installed then you can unplug til you wanna change it. They cost anywhere from 300 to 800 bucks depending on the brand or features. I would recommend Superchips, Bully Dog or Edge. Hope this helps.

Whats the advantage of a cold air intake on a 2002 Chevrolet Silverado 1500 5.3L

Installing a cold air intake kit like a K&N or Airaid will actually do both, give you a horsepower gain and better fuel mileage. you will notice better throttle response and you will not need to give it as much throttle to go the same speed as before and therefore you should see an increase in gas mileage(if you dont go hotrodding around!).

Let me help you kill two birds with one stone. I own a 2001 chevy s10 pickup. I wanted more power and better gas milage, so I installed a cold air intake. With a cold air intake, your engine will ignite more oxygen, therefore saving gas. It also boasts your horsepower quite a bit that you can feel in your performance. I don't know about those performance chips. There are rumors about them that they do not work at all.

Getting bad mileage on my 2002 Monte Carlo LS 3400 SFI 3.4 liter V6 and it is suppose to get 31/22 MPG can you tell me why this may be occurring? list the mileage for your vehicle at 29/19. I don't know what kind of mileage you have been getting, so I have nothing ot compare it to. You could be due for a tuneup, air filter and oil change. Scan the computer for trouble codes that may be stored in the computer and clear the codes. Keep your tires aired up to the max recommend pressure on the tire sidewall. All these things will improve fuel mileage. Great performance and mileage increase. Cold weather can affect fuel mileage as the engine runs richer until it warms up. The gas at the service stations has a lot to do with fuel mileage. Especially when they switch over from summer to winter formula. I got a boost in mileage and performance with a set of E3 spark plugs.

Ihave a C2500/ext cab long bed,GVR8600LBS w/7.4 vortec 4L80E and 4.10 gears.Iget 9 MPG Iwould like to get better gas mileage and more performance.[where do i start].

I have the same engine. I installed a banks powerpack on it and now I get about 14 on the highway and about 11 city. First thing is a tune up, plugs, wires, fuel filter, air filter, and that sorta stuff. I gutted my intake to let the engine breath better. The banks system opened up the exhaust quite a bit and it has alot more power and get better mileage. A chip can add some fuel economy as well. Any more than simple stuff like that, you'll start getting into serious money. My banks powerpack was $1800 and got me about 2mpg city and about 3 mpg highway improvement. Not much better on fuel but it did get alot more power which means I can be lighter on the gas pedal.

I have heard of many "chips" and "superchips" that are suppose to boost a cars performance - they range from £10 to £500 - Does anyone know if these actually do anything or whether they are just...

They aren't just gimmicks. Some do work. All they do is change certain key parameters of the engune. Remember the manufacturer of th car has to share some of the performance for better fuel mileage. Aftermarket performans chip makers don't care how log your tires last or the engine or trans longivity. If you get one get one from a performance supplier with a good name. Nody I know of will stand behind any damages that may result. Good luck

Where is the intake air temperature sensor?

if you look in the air intake boot you should see a two wire sensor stuck in it. this is the iat. That being said i dont recommend the "chip" you are referring too all it does is make computer think it is cold outside all the time so it adds more fuel to engine this is were they claim the extra power. decreased mileage and decreased engine life.a programmer works much better.

It ould be expensive to replace the cam for a higher torque range. Firstly, I would look p the torque curve on your engine and then try to keep the rpms at the peak torque rpms when going up hill. If this isn't enough, I would have someone put a power chip in your engine computer. Find a good reputation company though. The chip will usually advance the timing and deliver more fuel to the injectors. Ask what the chip spcifically does if you can. (Ford frowns on power chips, but if your warranty is uo, no problem.)

A last thing is to install new injectors that have a higher flow rate (lbs/hr) than your exsiting injectors. This will require the power chip though since your existing chip is designed for max fuel economy and not max power.

good luck.
