What you need to know is that Map 0 is not a true bypass map anymore. If you drive your car in Map 0 and use more than lets say 50% throttle you will get the half engine light. Your supposed to use map 4 if you want stock boost for everyday driving. And use Map 0 for when you take it in to the dealer only. Makes sense?

Is Map 0 a true bypass where it cannot be electronically detected by the dealer?
