Hello friends.please help me fix this jeep with edc16c31 ecu. i have done the egr and dpf delete but this vehicle still remains in limp mode. I dont get any boost pressure and not revving past 3000 rpm. i get error code for P2280 . there is o2 sensor heater error that pops up now and then also. the ecu does not change the wastegate duty cycle when i drive the car. i also get glow plug module power supply errors which i doubt will cause the car to remain in limp mode. any suggestions please.
