I went with the ZetecFD to reduce wheel spin due to the increased power and torque from the turbo. It's a nice mod and with it I can totally romp on it in 3rd in the dry and it just hooks up. 1st is still iffy and in 2nd it'll spin them for a little if I'm shifting hard and fast.
Aslo with the mod you can hit 60mph in second which lowers the 0-60 times as the V6 final drive requires a shift into 3rd to hit 60, IIRC.
