Thanks Bruce.

this goes to show what a terrible location the plans show for a cooling air inlet on the -6. Nothing like sucking air into the cockpit that's a good 10 degrees F warmer than what should be available at altitude for cooling occupants and avionics.
I mounted my OAT in the last bulkhead, under the empennage fairing, in the tooling hole. It does read high on the ground but by the time I'm at pattern altitude it is within one or two degrees of everyone else I have flown beside. One advantage to this location is that you don't have to worry about hitting it when cleaning the plane.

(Try using the search function, I just copied this from a prior thread on the same topic.)
I put mine there, and it reads 5-8 degrees higher than everyone else (RVs, Long-EZ, etc.). Thinking of moving it at annual.
Are you sure your probe is accurate?
Easy to check. Just compare OAT to CHTs first thing in the morning in the hanger (or some other long time period of constant temperature soak)... Usually mine are within a degree or two. Close enough for the purpose, I suppose. When the temps get close to 32F it is nice to have an accurate OAT. Perhaps one could soak the probe in a cup of ice slurry to verify accuracy at this critical point.
