Default TCS light staying off?

I have a 99 z28 and just put an ms4 cam, ls6 intake, and bbk 80mm tb on the car. The car is currently un-tuned (droping it off tomorrow to get tuned). The car runs and idles fine but after a few minutes of driving the tcs off light will come on and if you hit the button to turn it off, it won't do anything. It works fine for a few minutes. I wasnt sure if the problem was that the car isnt tuned or what. The throttle cable is tight and I have full throttle. Has anyone had this problem or know what the problem is? Thanks for the help!

Max KPA needs to be changed to 100 and the Minimum kpa needs to be changed to 0 with HP tuners.

You need to get it tuned and your tuner should know this. But just in case.

That should work for ya! Good luck.
