jporter12 Posted April 8, 2011 Report Share Posted April 8, 2011 for DTM Brian to get a discount on a tune? Quote Link to comment Share on other sites More sharing options...
kawi kid Posted April 8, 2011 Report Share Posted April 8, 2011 I bought this truck to tow and haul people and gear. Its not readable to hypermile in those situations. I started this thread looking for ideas to get maximum tune without spending hundreds of dollars which defeats the purpose of saving money.I already have $55 in plugs and 8 little 6" long wires are gonna set me back the same. What else can be done without breaking the bank?Mine has a k&n filter on it. Maybe a new filter similar to that would be a bonus. Quote Link to comment Share on other sites More sharing options...

Carwhore Posted April 9, 2011 Report Share Posted April 9, 2011 ive already sold that excursion lol.Look in your glove box and there is a white sticker with a bunch of 3 digit codes. Look at the G codes, what are they? GT4= 3.73 gt5=4.10 and g80= locking rear diff. What does your truck have for a rear end? Quote Link to comment Share on other sites More sharing options...

What else can be done without breaking the bank?Not much unfortunately, unless you want to buy a diesel. Or get radical with some fiberglass.According to the designer it uses 30% less fuel, and that's just based on aerodynamics (based on long hauls, not around town driving. I'm not giving an inch on the aerodynamics argument Jporter12 ) They didn't touch the engine at all. Quote Link to comment Share on other sites More sharing options...
Carwhore Posted April 9, 2011 Report Share Posted April 9, 2011 Sell it. Buy a 2500 suburban with the 8.1l (has the Allison) and swap a dirtymax in it.But seriously you should be getting way better fuel mileage. Quote Link to comment Share on other sites More sharing options...
Helmutt Posted April 9, 2011 Report Share Posted April 9, 2011 Check into Wynns Powercharge or their fuel system cleaner - this stuff boasts improved consistency in fuel delivery and enhanced performance along with improved mileage.You can buy through BrocksPerformance.com or possibly other online vendors - I'm going to try it in my bike for some "butt-dyno" results first then try it in my truck - but it is supposed to be good for any engine's fuel system Quote Link to comment Share on other sites More sharing options...
TwiztedRabbit Posted April 9, 2011 Report Share Posted April 9, 2011 (edited) i am going the sea foam route today just because its not been done... worked great on my other cars. my MPG isnt bad on my burban but its not going to hurt Edited April 9, 2011 by TwiztedRabbit Quote Link to comment Share on other sites More sharing options...

YSR_Racer_99 Posted October 27, 2012 Report Share Posted October 27, 2012 (edited) Whenever some sells you a car, knock 3-4mpg off of whatever they tell you it will get. They're telling you the best they ever got, that one time three years ago when they went all the way across Indiana at 60 mph on the highway.I agree with the Seafoam. Menards has it for $6.50. Full can in fuel tank (truck has 31 gallon tank. I added Sea Foam to about 15 gallons/ half tank). I had never used it until about three weeks ago. 03 Avalanche was idling roughly and the check engine light was on. Within ten minutes, idle was fine and CEL was off (still is). Don't know what it did, and I don't keep track of the MPG (wife's truck, and she has a lead foot. Keeping track of the MPG on that just makes me angry...), but I'll pour a can of Sea Foam in every few months.

sporttour Posted October 28, 2012 Report Share Posted October 28, 2012 I have found I get better fuel economy based on the brand of fuel. Valaro, Speedway and a few other ethanol blends result in lower MPG than BP, Sunoco and other first tier brands. Quote Link to comment Share on other sites More sharing options...
chevysoldier Posted April 29, 2013 Report Share Posted April 29, 2013 Not grave digging here...lolany update on fuel economy? Here's what my 08 Tundra 5.7L 4WD is getting. I'm going to switch to Amsoil next oil change. Need to check the plugs and see how they are. But at $10/ea, I don't want to. Quote Link to comment Share on other sites More sharing options...
