6 speed= 3.42s
auto= 3.23s or 2.73s.
The codes for the gears are on the sticker in the glovebox. It is the code that starts with GU and then a number. You can look them up online, I dont remember them off the top of my head.
Have a pro setup the gears, it isnt something to be done by an amateur.

Trying to remember that with the 6 speed manual its OK as the tall over drive still gives you some MPG.
