Just checked mine again last night..on a reprogrammed PCM (thanks to Jay) with 89 octane I got 17.8 in 100 heat and A/C blasting, all city.

Dennis,

What was your MPG before the tuning?

Well, at least you are buying good quality fuel for that price, although I don't think the quality is worth that much since I am still paying barely $3.00 for premim here. That should change here in a day or two. It would suck to pay that for crap gas.
