This is very helpful. Thank you. I was aware of the differences under Drive and Other. I don't have PTV or PASM. PSM appears to do the same thing in Sport and Sport+ (hard to read the chart on this one). So it appears the only real difference between Sport and Sport+ for my car when I'm manually shifting is in the dynamic engine mounts.
I've thought I felt just the tiniest difference between these modes while manually shifting, but it was so subtle I wasn't sure it wasn't just a placebo. Still not sure, but at least it could be something.
BTW, the PDK is great at shifting (way faster than I) but not so good at knowing when to shift (it can't anticipate - not that that's a surprise). Manual shifting is the best of both worlds.
