Turn off the nanny. With it on. If you lift a tire and spin it. It will kick in the traction control and kill your drive out of the turn. Also if you leave it on. It will apply a rear brake caliper to straighten the car out if the rear starts to step out.
Scare the crap out of me the first time it happen.
There is a YAW sensor in under the console. You can wire in a switch on the power wire to kill for the track. This kills most of the nannies.
Also with hard right turns. You will get fuel starvation. There is 3 fixes for it. 1. Keep a full tank. 2. Z1 has a new kit for this problem. Far as I know. No one here has used it yet. 3. Install phunk's RRP kit. I have, and a lot of others here run it too. It's a track proven kit.
