75 was stock, 72 will run with most of the same programing, 69 needs another belt and different programing.
Just an FYI.
I have all three but run 75 for reliability. I did not find a great difference in performance when switching to 72.

Hmm, interesting. Maybe it's not worth the effort then given that I already have the 75mm installed if the 72 doesn't make that much of a difference.
And pushing 12psi w/ the 69mm does seem like a bit of a stretch on a stock motor as a daily that I need to rely on to work everyday...
