Just set your max boost high enough (ie, 2psi higher than your autotuned boost pressure). And make sure that the dyno operator knows how to dyno a 6AT/7DCT without unwanted downshifts. And you should be good.
It also helps to turn off autotuning just prior to running on the dyno. Because each successful pull on the dyno will make the car detune due to typically poor dyno conditions (weak fan, no airflow, etc,.)

I really do have a more in-depth write up coming but just trying to find the time to finish it.

Yea he is referring to first having the car in manual mode so you can control the shift, and second making sure that the operater does not push the pedal past the kickdown...in the DCT or the AT if you push the pedal past the kickdown it automatically downshifts to the optimum gear for max acceleration.

Set the first setting maximum boost to 16 instead of 14 for both maps and you will not trigger the valet

Turn autotune for map 1 and 2 to value of 1 and then set starting boost to 50 which yields you 15. I am not sure if the n55 can support 15 psi at the moment but u can try

If you want it to only run 15...then just set it to 15 with no autotune.

However, I would set it to 14... with a maximum of 16 and let autotune do its thing.

Those turbo's have trouble breathing up top anyway. So I wouldnt push it. I would let autotune do its thing.

So the auto tune will only come into play with boost only correct? Not with timing and other things the procede is doing right?

So i can turn off autotune if i want 15 psi only.
