Well i took the lightning out on a saturday night to sonic to get a drink. I was parked there and a blue sierra kept going around and everytime he passed by he would rev his engine. I told myself that he wldnt have a chance. As i left he parked and waited for me at a store. I told my wife that i was guna see wat he had. We had a red light and when it turned green i gunned it and spun a lil nd jumped him about 5 cars and after that he didnt rev anymore. My lightning has longtube headers, cai, 4lb lower pulley, full exhaust, and a tune. The sierra had a 6.0 longtubes and tune. 2000 GMC Sierra Custom now hes selling his truck haha
