i was wondering if anyone knew were i can go to get a valet key installed on my mustang, or if there is something else i can do so i can control the power output of the car. in example someone else using my car and i dont want them messing my car up and want to give the limiter power, rpm,speed limit. i have heard of putting a valet key and when using your original key it unlocks full power. would appreciate any ideas on this. thanks!!!

 

if you have a handheld tuner, usually
you can limit the top speed and also
the rpm rev limit.

 

The 05-09 S197 does not support 'valet key'.
All the 2010 Fords do this year.
And radio volume limiter as well.
Pull 2 or 3 plug wires and valet mode is a given.
