I have been running them for about a year at 10.5:1 compression. 10.8:1 would make them work better, but that's getting high for a Texas biker like myself.
I just did my 2014 107" with tman 590 haven't put miles on it yet because of snow but the idle has a nice lope to it and the snap of the throttle is crazy good. I also did stage 2 heads and fueling cam plate kit
I have tuned a couple of the reaper and they did well but the t-man 590 at the proper comp (10.6 to 10.8 to 1) and some headwork NEVER disappoints. I have probably installed and/or tuned a couple dozen at various cubic inches. And I wouldn't consider this splitting hairs, these are two VERY different sticks
