I usually reset the MPG'S after I fill it. I filled my car a day or two before the tune, and then I filled it today....this was my result

obviously I can't keep my foot out of it....

sorry about the dashboard dust...around these parts, cleaning cars out when its cold is like woman shaving their legs in the cold...ONLY IF NECESSARY!

 

Come on you can burn more than that, I can average under 15 if I try......

But it got 30.1 on our recent road trip, except for the hwy 101 twisties, probably 12 there...

 

The one day I tried on my way home from work it was over 28 mpgs with the stock tune(awesome feature to be able to switch tunes in the blink of an eye) it seems like its like 3 mpgs less tuned then untuned, when watching the instant mpg thing....the one time at a constant speed I was messing with the button on a flat road...I seen 41 INSTANT MPG, then switch the tune on and I seen 38 INSTANT MPG....seemed consistantly 3-4 mpgs lower with trifecta....but its totally worth it...

 

Geez..I can get 17 while cruzin at a buck twenty five !
