The After Dark Speed 2002 C5 Z06 started out as a bone stock Z06 that had a severe engine miss above 4000rpm. I simply loaded a stock 2002 Z06 tune using HP Tuners and then the car ran perfect. The car was then completely stripped down mechanically and built into a street legal time-attack car. During this build process many of the After Dark Speed C5 products were created along the way.
