what gear ratio do you have

[inh]

I have 4.10s on 31" tires.. and i get like 14mpg city.. Im sure if i worked it right i could get 18mpg on the highway.. I drive mostly city but ocasionally i go offroad or drive the freeway.. I'm thinking of bumping up to 32 or 33" tires, but i think the initial strain of getting started from a stop would offset the higher speed gains.

Hmm I am calculating this but what type of trany do you have and whats your milage?

5-speed M5R1

last fill up was with 17.6 gallons at 306 miles

17.35 miles per gallon? something like that.

Hmm well I maintan my truck. I do every thing. I even make my own octain boost.

Seafoaming might help, driving style has a lot to do with it. But i really do dog my truck around and still get the same results.

4.10s and 33"s, even 35"s is completely dooable. Its all in how you drive it

33"s and 4.10 would be fine. you might be more comfortable with 4.33, 4.56 for that extra UMPH to get it going.

Hmm well you said you have 3.55's and 31's right? Do you have any vacume leeks?

 

[slravene]

not that i know of, whats a sure fire way to find out? and i need to replace my plugs and wires, that should help right?

spray WD-40 and see if any looks like it gets sucked in.

if you dont hear any excessive sucking noises comming from the engine you probably dont have any. Vaccume leaks some times make the truck sound like a fregging jet, and usually is accompanied by a high idle ~1000+ rpm

plugs and wires might help. Cleaning MAF and IAC can help out.

Try Seafoam, that might get you up to 250-275 miles a tank.

Umm replace the plugs and wiers if needed I havent had to for a few years. Also trany fluid filter oil. Umm as for detecting leeks well thay reqiers a few things to do it. I prefer to do a propain leen on my cars to make it emmishens legal and to find leeks you could do the same but. Im not in you area so I dont no whare will will get the tools needed.

Do not use WD 40 it will slowly eat ur hose! Its a high carosive if I recall and dwars in moyster and can cause rust.

sometimes after a long higway drive in the hot heat (about 175 miles in 95+ degree heat) the truck will have sorta high RPMs after i stop but leave it running, could this be bad?

I bleave that is cause the computer gets comfertable at staying at a set rpm. Also it has to ajust for elvation. I drove to phonix with cuse all the way and when I hit a light their I felf the brake and herd the rpm so I shut off then on the truck and it reprogramed thats how to fix that.

O and the hoter it is the less dence the air that could also afect you.

If this is not ur case ill have to talk to my dad since he has much more Exp. In the Automotive feald.
