Let me re-phrase, I was unclear.
Are you suggesting that you had a 5 MPG gain in your commute to work (HWY portion) as a result of the tune, premium fuel, and perhaps a bit from weather related variables?
I understand Vince is brilliant, I have no doubts about his skill set. But I have a real hard time believing my powertrain guys left 5 MPG on the table for no good reason. 1 or 2 by being gentler on the trans for the sake of lengevity, OK. 5, if that is just from the tune means we are paying the wrong guys!
Any chance we can get you and GDubs to hook up for a nice trial? Say 5 days of two way commutes on stock tune with 87, stock tune with 91, and then Trifecta tune with 91? Im sure Vince will pick up the tab for the gas mileage lost during the non tuned weeks - as an advertising expense

. Youd have to be diciplined to try to keep your drving consistent, which is pretty boring. I am really excited about the results you have so far, just did not expect that kind of gain. Very cool
Dont really care if its DIC or calculated, as long as it is all apples.
