says no matter what you do you aint gonna get more than 474-500 hp out of the car on pump gas. unless you like to hear a pinging sound. The car will be driven every day in the summer. want to smoke: Z06 , cobra, viper. not going to race this car. Want a fun fast car. JWT said get the sport 530!!! very hard to pick the right shit for this car. thanks for all the feedback.are the 530 the best choice???
