CVOthunder, if i already had a SEPRT, I wouldn't even consider swapping it for a Powrpro. There's absolutely no reason to do so. My impression, with what I've gleaned from different sites, is that on metric vtwins like M109s and Star's 113 motor, the Powrpro outperforms the other tuners like you said. On Harleys, however, I don't get the feeling there's that much of a difference. There are lots of different tuners to choose from for Harleys with EFI, and lots of people have spent hours optimizing their performance.
I was stuck north of Rexburg, ID once for 3 months in '84-'85 Dec thru March. Temp never got above -40F for 3 days once. Never want to do that again.
My wife grew up in, err, outside of St. Anthony, me from Oregon coast, and she cannot believe how dry and warm it has been here this winter in Boise. It has a lot of mountain ranges blocking most of the worst weather and in this type of weather pattern I ride all the time so far!!! And I have fairing so some light drizzle, rain not snow, isn't a big deal and it rained alot if my memory is correct at the coast of Oregon and the Willamette Valley. I learned to ride there and spent the first 30 years riding in some wet stuff so no problem!
