need some info on gettin more out of my truck

[darin95yuk]

alright guys i need some info on getting more power and fuel economy i was just wondering on what gas miliage your rigs get and how many horses you guys got? mine is a stock motor 5.7 with a 6in rough country and 35s 3.73s yadayadayada i think im getting about 10 to 12? i was wondering on how to tune a pcm? and a cold air and headers... dont want to spend alot because i want to eventually go to a 6.0 and a 4l80e in my ride... just looking for something to help out for now...

I'm guessing by your 'name' that it's a 95?

Im getting 13-13.5 mpg, K&N intake, dual flowmaster muffler and exhaust, accel cap and dizzy cap. I do need to change out my wires and plugs. As far as wheels goes, im running 31" BFG KM's and i have stock 3.73 gears (soon to upgrade to 4.11's). I don't have a lead foot, so im babying the truck so i can get better mpg's especially the way gas is going....$3.65/gallon

I have a completely stock engine except for dual flowmasters and I get about 12 mpg and Im pretty heavy on the gas. Doesnt 96ProComp get like 16? Where is he at??

i have a stock motor. besides k&n filter and flowmaster exhaust. im easy on the gas unless i have to be hard... i get 13-14.5. thats mixed driving.

sounds normal for a lifted 4x4, adding a 6.0 and 480Le isnt gonna change that

LOL @ 3.73s and 35s.

You can get more power out of it but you should adjust those gear/tire ratios to get it better.

Also with these TBI trucks you have one or the other, fuel economy or power. I did a Vortec head swap and am making alto more power, I'm using way more gas too.

just filled up a couple hours ago on ($80 i'll never see again...) and averaged 15.99 miles out of the last tank

lifted, geared, headers, CIA, etc, etc, etc, hoping to get a couple more out of it when i get do the PCM swap/tune

 

[SunlitComet]

Procomp what size gears and tires do you run?

 

[darin95yuk]

i know the 6.0 isnt gonna help much but ill have more bang for my buck when it comes to balls... and they average 18 in my father in law 2004 suburban with a 6in lift and 37s... anyways how do i go about modding and tuning that stuff and what does it do? what is a cia and a pcm?
