I have a problem with my cat. I have a hard time hooking up off the line in first, so sometimes I short shift to second to minimize the spin. Should I play with the air pressure in the tires. I have mild mods, Ice man intake, and throttle body, under drive pulley kit, svt fly wheel,and custom exhuast, high flow cat, 3" pipe through a cherry bomb glass pack, which I burned out the glass! The whole front end starts to bounce when I launch.
