Thanks Jake for the explanation. That was great. I was under the impression that 27 psi was the limit for the DCT and you couldn't change the the third cell PSI value and that's why I was changing the second cell value to change slope of the line to get headroom for DCT cars. Now it makes sense and by setting the third value to 33.26PSI you are only sensor limited which is great. I think there's bunch of others who didn't think of changing the third value to get full range of the sensor.
