has any cai or the jwt popcharger help with your gas mileage? im all stock right now but considering getting the popcharger if there are some mileage gains.

 

not really

 

If you are interested in performance, an intake is a winner. If you are interested in improved gas mileage, adjust your driving habits.

 

Well I just drove from California to North Carolina and I have a Megan Y-pipe, JWT Pop Charger, and Apexi exhaust. Now I had my Z weighed down with TV, Xbox, Cloths, dishes, etc. The first time I made the trip I got 26.7 on the highway. Went I went back I got 28.1 (With the mods). If you ask me the parts will save you gas. But once you hear the wistle.....Trust me the gas saving will go down : )

+1...any breather mods will increase your MPG theoretically...but you give it more gas so it kind of evens out On the highway though I believe it will make a difference.

 

I second that. Add on the exhaust after that...Might gain 1 or 2 more.
