There is NO power...feels like it's running on 3cyl. I drove the car to lunch before the install and it ran perfectly, now with the heat exchanger in the car feels like half of the motor is gone. Did we miss something in the install? Is there something in the diagnostics and/or setup in the JB4 to account for the new hardware? Please help!!!
