Well a map sensor throw a check engine light when a turbo boosts? Are there any sensors in the throttle body and intake manifold of a 1.6 LC2 that will throw codes in the ecu when a turbo boosts? What might be some problems that a turbo can cause? Does anyone also know what a safe max boost level may be on a stock lc2 motor? Just trying to find out all I can before the turbo project begins with my brother and I this fall and finishing into the spring.
