Anyone ever "tuned" the wifes car and not tell her?

[Woody]

I went to a dealer, got my car appraised and had a deal all lined up on my ecoboost. I told the. It was pending a conversation with my wife. She says I bought the car without talking about it. She is joking and doesn't care because I did it with 0 down and no change in my payments. The night we talked about it she says "I wonder how long it would have taken me to notice if you just bought it."

In her defense, I did just go from a blue mks to a silver mks. Just so happens this new one has an ecoboost.

You could just do what I do; make sure when you talk about the cars and performance and such you drone on long enough with techie details until you can tell she's tuned you out, then start to transition into alllll the wonderful goodies you've got planned (BUT, make sure not to look too excited...they can sense your happiness and that sends a signal that you must be doing something you're not supposed to, so that will snap their attention back), just stay nice and monotone and keep blah, blah, blahing right through all the important stuff.
THEN, after your install, when the wife's all; "WTF!?" you can just say; "but babe, we talked about all this, don't you remember??"

An important note here is this: Sure, this has worked every time...but it's been on GIRLFRIEND...and not WIFE so be careful!
I was married once...

The wife drove my SHO all day today.  Not a peep about the extra performance it has with the tune now.

She knows I bought something but has no clue what.  She signed for it from ups.

2 things.

#1 just goes to show that a tune does not affect the drive ability of the car day to day.

#2 my wife just expects more power and her xsport needs the tune as well

I can't speak for the other tunes, but every tune I've had on my cars has been very driveable and for most drivers who are like my wife, they rarely go past 1/2 - 3/4 throttle it's no big deal.  But on the Lund SS tune that has most of the torque management disabled, if you got WOT it will torque steer, and if the road is rutted at all, it can pull pretty hard to one side. 

Nothing that is uncontrollable, but something that is good to know for that once in a blue moon your wife has to floor it!
