what is the cheapest way to get better gas milage

 

straight pipe exhaust. cold air intake. programmer maybe

 

i put straight pipes on it and i get worse because i love to step on it and hear them things rumble

 

I know what you mean. i got the same problem lol it's addictive

 

yeah, i'm with yall on exhaust... i'd get a throttle body spacer

 

K&N filter, TBS, free up exhaust a little.

 

What year-model truck? The newer trucks with the 5.3L need a little bit of back pressure. That is probably why you lost fuel milage when you went to straight pipes. I think that I lost some on my truck too when I put true duels on my 98'.

 

Does anyone else use this water4gas systemI'm thinking about giving it a go toincrease my gas mileage.

 

actuall i have the true 350. 1995, 5.7

 

so how does the water for gas system work
