Im swapping a 95 cobra motor and 5 speed from a totaled cobra into a 95 GT. My question is how well will the car run with the cobra computer no tune and stock 24 pound injectors with the motor having twisted wedge heads, TF stage 1 cam, 70MM throttle body, Professional products typhoon intake. Should i get a tune or will it do descent since the cobras already had HCI that were a little closer to my combo that the GT's were.
