Quick dyno questions

I'll be taking my 08 A6 to a dynojet on Tuesday, and I had 2 questions.

I have stock C6 wheels, but am running the 265/35/18 front and 305/30/19 rear tire combo. Does that need to be adjusted for on the dyno?

Should the car be in competitive mode or TC/AH off altogether (ie the 5 second button press)?

Thanks in advance.

I don't believe there is any adjustment needed for tire size and the tuner should know what to do with the traction control. They shouldn't have to mess with it.

Turn the T/C & A/H OFF. Turn the A/C OFF. Dyno in 4th Gear.

The computer will be confused enough with the rear wheels doing 120MPH and the front wheels not turning.

Thanks, that's what I thought, just wanted to confirm.

Should have the #'s tomorrow afternoon, TLTONEY.
