I have an 04 gt with a 75shot ,cold air intake, Ud pulleys, mac catless X pipe, flowmasters, trickflow upper plenum,. My best e/t is a 13.4. Im trying to reach 12s without supercharging. Want to do it with a chip and gears. What do you think? Which chip and what gears?

 

predator and 4.10s and some drag radials, w/o them you will spin all day off the line

 

You don't always have to go full throttle off the line.

 

Get some 4.10's and some slicks and you will see 12's easy. I made a 13.0 with these mods and no spray.
