I mean really? Are people really this ****ing stupid? These cars are on the verge of KR from the factory with the 3.8" pulley.....Then those same people ***** about how slow their car was (from the retarded amount of timing being pulled, no pun intended) and how the motor blew up in "that pos GTP they used to have"...... To the OP: The only mod that is gonna make your car faster is an owner mod.....aka one with a functioning brain...
