Its running real good now on the 6 cylinder tune Bill sent me. Drove it around my mountain top with no mufflers, just 4 feet of pipe. Instant throttle responce and quicker acceleration. Also, starts instantly as soon as pedal is pressed. Just got to get to the exhaust shop on my day off and he isn't booked up with other clients cars like last Monday. Got 2 Porter Steelpacks to put on it. Jim
