I got the trifecta tune at the recent sale, and have not yet installed it but did download the files and read up on how to do it. I was going to tell my wife it was for "us" for christmas...but I'm rethinking that approach...Figured maybe I'll just install it and not say anything. Do y'all think she'll notice? 
She's not a racer or anything but based on my many years of marriage and using DIC MPG on various cars I know she's more leadfooted than I am in daily driving...
wondering if I could just tell her its because we have colder weather lately or put premium fuel in or something.
