None of the information you provided matter....(kinda)
1. by a scangauge
2. find a flat section of highway close to you
3. using scangauge, run up 6 miles, reset, run back.
4. do this for 50mph, 60 mph, 70 mph.
your looking for the sweet spot in the rpm curve.
On my Infiniti Q45 it was around 1780 rpms

Second, how much freeway driving total miles a yr, do you do?
MetroMPG: "Get the MPG gauge - it turns driving into a fuel & money saving game."

First: ScangaugeII

Second: Grille Block

Third: Full underbelly pan

Fourth: rear skirts and 30.4mpg on trip!
