Correct. The % duty cycle is calculated based on the sum of the line pressure adders divided by the "max line pressure" scalar. After driving around with a real line pressure gauge on multiple 4L60Es, they usually run around 65-70psi with no load, up to a max of 200-230psi at WOT in 1st gear. So when I saw "90 psi" in Tunercat, immediately my BS flag went off.
