2007 4.7 mpg

Is there any gas saving/ MPG boosting mods or add ons for this engine?

When I went to buy the trans app it wouldn't let me buy it a b.c. it said my card was expired but is good thru 2012...

Im using the 87one octane tune on advanced mode although all I've done is change the top speed. Wot. And tire size lol...

I had to take the tune off a few weeks back and lost power and gas mileage so I was quick to change it back

4.7 mpg is ridiculous. either your commute is so short it never spends time warm, you spend 90% of your time stopped, or there is something wrong. I don't think even cräppy driving techniques will yield mpg that poor.

you don't need a mod. you need something fixed.
