Mein Auto: 2013 550i xdrive
I haven't dynoed my car yet, but my shop uses a Mustang dyno. What is the issue? Is it the 8sp Auto? I'm thinking it will be somewhat of a PITA because of kickdown.

I was going to try 4th, 5th, and 6th gear. 6th is ~1:1 ratio. This is my first automatic, so I always want to floor it, but you are at WOT without hitting the switch to kickdown.

Good luck

Hey. yeah, 8 speed auto. Shop was having trouble getting a tach read, and also staying in gear. It was pulled in 4th, which i think was the wrong gear to pull in. like you said, 5th or 6th. way inflated numbers, but just doing it for a baseline before a tune.
