I also have the perrin stage 3 map and today I tried to launch my car, which is set to 4.5k for some reason, and after setting at 4.5k for a few seconds I was about to launch and boom check engine light and the car was a slug. I whipped out the AP and it said P1238 (torque limts) I tried to reset the parameters and switched maps and it still wouldn't go. So I started and killed the car about 10 times and it went away. I need to get to PLano and get a custom tune by Cobb.
