Hello, so I own a 2005 Honda Pilot with 89k that my wife drives, and a 2014 Ford Focus ST with 15k that I drive. I also recently picked up a really well maintained 2001 Pontiac Grand Prix GT with 83k that I will be using to commute about 80 miles/day pretty much all highway. I really like it and have driven but never owned a pontiac.
I've been browsing this forum for a few days and there is good info here for sure. I'm fairly active on the focusst.org as well as radar detector forums as I'm a Rd geek
Anyhow, since I'm only commuting highway I was hoping you guys could chime in on the best ways to max out mpg. Is there a specific tune/calibration I can buy (the cheaper the better), how have people done with k&n filters? Or whole intakes? Over inflating tires? I'm guessing a tune will be the most beneficial but does anyone sell one specifically for economy? Thanks on advance!
