2010 g37 tuned on Ecutek Dealership installed a new OEM flexplate with all the pins and got the car to start. The problem is when it turns on it’s still in limp mode and keeps throwing the same codes. P1088 - VVEL System B2 P1093 - VVEL Actuator Motor B2 P0335 - Crankshaft Position Sensor/Circuit They dealership is now telling me they can not further diagnose it without flashing my car back to stock and even then there’s only a 10% chance of “it” working. I’m already $3200 into it and NOT about to have them flash it back to stock. Anyone know why this is happening or had experience with this before? TIA
