Just wondering once ordered how long until it is shipped? Also I have a 2003 Mach 1 with 4.10 gears, K&N Cool Air Intake, Flowmaster 40's Mufflers. What do you think that I am going to gain from the Xcal 3 tune?

 

If I remember right it takes them a couple business days after its processed to program the tuner. Gains I'm not to sure for your exact car I would guess maybe 10wrhp

EDIT: Taken from the AM site: "We suggest placing XCalibrator 3 orders with custom tunes separately so that it will not hold up your order. SCT orders take any where from 5 to 7 business days to be custom tuned from the time you supply us with your custom tune information. Please keep this in mind if you need expedited shipping for an SCT order. If you have a stock Mustang and are having it dyno tuned, please select "No Thank You" in the free custom tune drop down box above to expedite your shipment. "

 

We list 5-7 days because it can get backed up during some of the busy times of the year...race season, Christmas, etc. But right now, I think they are taking 1-2 days from when you submit 100% order and information. - Nick
