I got Superchips Flashpaq F5 refurbished (full warranty, 30 day $ back) for $229 so it's hard to swap that for a $500+ street tune or another handheld. My local tune shop starts at $500 then adds dyno time at $275 hr.
Superchips tech said yesterday that I could run performance tune with 89 but I'm leaning towards just 91 octane all time. If I notice any decent mpg/performance gains on 89 or 91 I'll post the results.
