It's not the "horrible nature" of the Cobb OTS tune. The Cobb ots map is likely one of the kindest and safe OTS tunes out there. It is not, however, meant for a built motor along with your other modifications. Your ecu is protecting the motor. I would get your car pro-tuned ASAP before you experience the "horrible nature" of buying another built motor.
