I am trying to save a little more fuel for my car any recommendations for a programmer for better fuel economy?? and anything else that could help save more gas..

Thank You.
 


The biggest return on your money will be to make sure your car is running like the engineers designed. A Tune will cost a minimum of 100 dollars, and you might get 1/2 mpg better, so it will take a while to pay it self off.
 
Any recommendations then Sgt.??

my $0.02 would be clean air filter, MAF& throttle body, properly inflated tires, good spark plugs & wires, limiting idling/warming up & heavy right foot(keep it under 70 mph), removing any extra weight (junk in trunk), use cruise control when possible, and make sure it's full with clean fluids.
 
if your Upstream oxygen sensors (pre catalyst) have fifty thousand miles or more you could pick up a decent bit with just replacing them. Over time they skew off of proper stoichiometric and cause you to burn more fuel than you need to.
From what I recall it could mean an up to 3% Improvement
 
spark plugs, wires, air filter, making sure the car has no leaks, proper tire pressure and alignment. if you can change your driving habits that will help as well. I have a Chevy Cruze with the 1.4 turbo engine, and my wife get's 3-4 mpg better than me because I have a hard time not accelerating fast, the gains in driving habit may not be as substantial for you, but you get the idea.
 


Ive just replaced that spek plugs and wires, all OEM to and my mileage got worst. Exceot the fact that on the freeway its better but short distance, stop go alot it got worst.
 
Roger Sgt will on the Stop go On JBLM, my mileage got even worst then before, but Freeway i get really good millage.
 
not good use to be approximately 17 mpg , now it drop dramatically when i changed the sparks out and wires also. on the freeway i see a big big difference though, i get about 26-32 mpg, but when im on JBLM, because thats where i am all the time it went from 17 to 14mpg

What kind of mileage are you getting now?

Like said, clean the MAF and change the o2 sensor if it's the original.


No programmer or tuning software like HP Tuners is really going to help you with MPG. It's not easy to get better MPG in the city with stop and go type traffic.

Getting rid of DOD and leaning it out on the highway on pump gas net me about 25~. But that was with 3.69's. I always seemed to average about 15-16~. Who buys a V8 car for mileage, anyways?
