brr... lowest I seen is -2.
fuel ecomony only shows about 15-18mpg on my trips to work now, 5mins down the road kinda thing. I used to get average 37mpg and up to 46mpg on my 80round trip long commutes. But then I had to fill up mid week, now if i didn't travel over the weekends I wouldn't have to fill up a couple of weeks

although, I think my mpg has gone down a little since fitting exhaust, do I need to reset ecu for it to readjust?
