Well my buddy bought a 2013 and its go longtube header exhaust and intake. He went last week and could only muster a 12.1@121 with 1.99 60' with nitto nto5. He was afraid to take off the traction control. We im gonna drive it on Wednesday and need some pointers. I know I have to take off the traction control. What psi should I be running on this tires? Please give me some pointer as we are betting dinner for who ever drives the car faster.
