3.73 are fine with me.

Be sure to do some aggressive driving (a.k.a, WOT) just before you load the new tune, then repeat the same trip. It's best to have a fresh feel for the car being stock when you head out to feel the new power.

i might take it to the dyno and run first one stock..then next 2 on the tune

I'm very curious as to how just the tune w/o the CAI works out on your 2010. I was contemplating the CAI/Tune combo, however, I'm not sure I want to do any engine mod right now with the car beiing so new. Also don't want the hassle of having to switch out the intake if I have to take the car in for any warranty service as well as concerns about issues with state mandated emmisions checks on annual inspection.

Keep us posted.

Geez, warranty wusses... I took my Stang in for warranty work on a few occasions and left the CAI & tune installed. No hassles. Unless you expect engine problems, just do it.

The CAI & tune on the '10 doesn't provide as much of an increase as compared to the 05-09's for 2 reasons:

1. The stock tune on the '10 is basically a "tweaked" 05-09 stock tune, same as that on the Bullitt. The custom tune will still provide some gains on a '10 but not as much percentage wise over stock as occurs on an '05-'07.
2. The stock intake on the '10 pulls a bit more air than that on the '05-'09's. A CAI & custom tune on the '10 has a little less EXTRA air to work with than a CAI & tune on a '05-'09 which again results in a smaller percentage of gain over stock.
