Fuel Optimizers
Does anybody know of someone using fuel optimizers?
gas is getting expensive and need to think about ways to raise mpg.
ive heard of performance chip scams so is this even worth checking into?
i found this link on them - http://www.improvegasmileage.com/
thanks.

alright, any prior use of it or just other research like what ive already done?
which injectors do you use to swap? ive heard of neon and crown victoria injectos. i think i remember something about a 503 number with them?
what about just aftermarket fuel systems such as fuel rails and different fuel pumps and fuel presssure regulators?

Complete waste of money.
As far as injectors go i went with 2003 crown vic 4.6 injectors and they do give me a little better gas mileage and it does idle smoother.
The dodge neon injectors are 703

^^ x2. Don't waste your time with the fuel rails, pumps, etc. The results aren't worth the hassle. Just do the injectors (703's from a neon/stratus with the 2.0)

Hmmm. Injectors? I don't know wat was done to my jeep, but the wheels skid wit very little water on the ground! I have a K&N. It's just regular care monthly on them.
Injectors?? I might look into that. I might have a good but bad set. Might be why it drinks gas! But it accelerates like a Honda!

For better mpg,s change to cold air intake, new coil, distributer, wires, get high performance such as accel. higher throttle body. And new gas filter, This should help..

The platinum 4 works great. No rough idle and great acceleration. Used on an 89 and my 01.

i remember reading about one of these http://www.fitchfuelcatalyst.com/ in off road magazine a while back. the mag is geared towards prerunners but they said it increased their mpg by a few miles, might want to look into it. ive never used it but maybe someone here has?

Basically dont drive over sixty.. and accelerate slowly.
Also correct tire pressure.
But aftermarket parts.... not really. Marginal increase in the injector upgrades, but thats about it.
