Its just a way to custom tune the car w/o voiding the warranty. THey see no signs of a chip theres no BS to deal with. SO yea it normally wakes the car up esp one thatsgot power adders to it.
Let Mustang Magic do the tune. It's better than an off the shelf chip cause it's tuned just for your car right there on the dyno, if you car doesn't like the tune for some you reaon you can go right back and have it adjusted without worring about mailing a chip back and forth to whereever you purchased it, and they know what they are doing over at that shop. As a matter of fact I just had my car tuned and I glad I did. It cured a lean condition I was unaware of as well as giving me some more power.
