Hey All,
I have a V6 mustang and was thinking about putting in the M-2007-FR1V6 Performance upgrade pack...but with the fuel prices today, I am questioning it as they say I would have to start using premium...My question is why exactly??? Is it because of the 90mm filter allowing more air, therefore changing the air to fuel mixture ratio? Or is it because of the Calibration that would be done???
