Hey silver!
Sweet ride- just snagged my second HX recently also a Vogue Silver 99 5MT.
Very capable of astounding mpg's
I'm more of a "drive it" owner, keep it tuned up with the basics and enjoy what that car can offer. I've found that real hypermiling techniques give better results than the lean burn feature everybody squawks about, but as usual YMMV.
I am a ScanGauge XGauge fan but am just investigating the Torque Pro app via BT. I seem to recall seeing iPhone compatible in my research. Give it a search and see if it works for you??? If not, the ScanGauge has been my mainstay for nearly a decade. It works well for me.
