From: ECS : WTF did you break now and HTF did you break it this time
1:1 ratio is most accurate with no torque multiplication etc.
obviously glides and turbo 350/400's are a bit different, but you're looking for that 1:1 whereever it is in your specific trans

I have an auto and it was dynoed in 2nd on a Mustang Dyno. I was told that is was unsafe to run it in 3rd with my 2.73 rear. My numbers were lower than I expected. I asked about it on here and got various opinions. I googled and it seems to be a common practice to run in 2nd under some circumstances. I also found some posts about damage from going in 3rd, with high rear gear.
I was told my car would dyno quite a bit higher if it was a 6sp with a 3.42.

From what my tuner has told me its knowing how to calibrate your equipment. He prefers closest to 1 to 1 as possible but says not all cars have a 1 to 1. I think sti's need to be dynoed in 3rd. (no one to 1)
Ive seen more than once operators not know how to get it to dyno correctly with out the auto kicking down. I ve also see operators do 6 year pulls on my buddies C6 lol can you say 200+ mph wheel speeds.
Ive been guilty of using cheaper priced tuners and have bit me in the ***. I found a guy literally in my back yard that knows his stuff. I hear his dyno from my house running m-f all day long. Guy has a waiting list 2-3 months to see him.

What kind of dyno does he have? Has he told you that he would dyno an A4 with a 2.73 in 3rd, with no more risk than running it in 2nd?
