2005 Mustang gt TCS questions

I have an 05 gt that has been tuned with an SCT Xcal 2.

My question is that on the handheld it is possible to disable the tcs permanently. Thing that concerns me is that does pushing the button in the car to disable the tcs do the same thing as disabling it through the programmer. I know with some vehicles such as mazdas that pushing the tcs button doesn't always turn the tcs completetly off. Even with the button pushed the tcs system will still kick in when it senses the vehicle is out of control and will still limit power.
Just wondering if fords tcs system is as advances as this or if once you push the 'tcs off' button that it completely turns the system off.

Thanks

I'm not 100% on this, but I think it is not completely off when the button is pushed. The last time I had a tune done (2 years ago) you had to have it written right into the tune to have the TC completely disabled. Might be different now.

TCS off is off. Same as disabling in the tune.

A good way to mod the TCS switch is with a relay. Here is a link that shows how to do it. Works great and takes about an hour if your handy and have some tools. Every time you turn on the car the TCS goes off. If you want it back on for a rainy day just push it on.

Pushing the button to turn it off will keep it off until you either push the button to turn it back on or turn the car off and restart it. I had mine turned off when I had my last tune written. It was a pain to turn it off every time I started the car. I didn't have TCS in my older cars so why start now?

RWHP/RWTQ is adequate
