Overdrive

[30psi]

5th is over drive, purely because its over driven.

Worth checking your speedo against GPS but chances are your doing closer to 70mph even if the speedo is saying 80

yip, 1,2 and 3 are underdrive, 4th is 1:1 and 5th is overdrive.

the auto is fine and makes the s12 a nice car to drive, ideal daily driver infact. not overly exciting though and I wouldn't bother with tuning an auto at all

I would second that. My s12 (when she was running) had an auto box. I tuned her up to just over 200 bhp at the wheels, but the auto box couldn`t handle the extra power. Kick down and the car would red-line before the auto box had chance to catch up with engine speed.
I had to have the box reconditioned three times cos it kept blowing seals .

Great motorway cruiser though and still very quick (when she was on the road ).
