The CTD is a longer stroke than the PSD and requires less RPM to make its power. This was the hardest part for me to get used to after running a PSD for 10 years. My CTD runs with 4.44 gears and my PSD had 3.73 ratios. Since I rarely drive over 65 mph, I don't need tall gears and am happy with my current combination.
