Power Vision Information Thread
Some of the confusion is present because Harley is constantly changing their calibrations, so we can't blame the PV for at least some of the arcane rules and configurations that we see.
By "air foil" do you mean the type that mounts to the outside of the forks (58121-85B)? If so I don't know if they adversely affect cooling, but I had them on my old RK Evo and oil temps almost never exceeded 180° even in summer traffic. I have lowers on the '07 SG that are supposed to help a bit, and I did notice a small change after installing them.

I just noticed that you have a 103 and my understanding is that they run hotter than the 96, quite a bit according to some reports, which may be why they install oil coolers as standard equipment on these. Maybe some other 103 owners can report the ETs they're running. A friend who has a Stage II (103/255) Ultra runs fairly sane oil temps, never higher than 230° so far since installing his OTG, but he has no way to monitor ET on his bike.
The 255 cams are supposed to run hotter than most performance grinds, I presume because of the early intake close of 25°, but I don't see any meaningful increases since installing them three years ago.
I would get a grip on the detonation you're seeing in your logs, although if you don't hear it I wouldn't think it would be enough to affect cooling since the KR function is dealing with it. Uncontrolled detonation can cause overheating, though, as well as produce more dire effects.

Sometimes adding a little cranking fuel at that temp will help.
