I just got the RCD race tune and ran against a Chrysler 300. He thought he was going to blow my doors off. I launched at about 12lbs and he took off before me. I beat him by 3 to 4 cars. All he could say was it took off like a jet. haha It's definitely not something to drive on the street. It is a track only tune and sure pulls hard. I will get some numbers this weekend if the weather permits.
