But the 30 was from city driving too? That's what I was getting at.

Hmm, so you're running an unknown speedo sensor and you think your speedo or odo are going to in any way be accurate?

Stop and go rush hour highway and around town. No real cruising.

Alright, two things Ben, 1) is there a thread somewhere with all of your current setup specifics listed? 2) How long did you spend tuning to perfect your fuel economy?

No--vB garage is quasi current

A couple of weeks, actually like 1.5 wks probably for the street tune that's in it with the HR firmware. Spark map is based off my dyno tuned standard code spark map, just advanced some more in cruise. I'd like to dyno tune this set up, but it doesn't make sense to spend the money right now.
