Dr. Bert and myself live in the same climate at about the same sea level. I'm running an 80* unit with the manual transmission. I can tell you ditching the autobox dropped my temps to the point that the car runs around 70* at the temp sensor on the coldest of mornings and around 90* on the hottest of days. I think the car is very happy with these temps.

With the autobox it would run between 90* and 110* back when I was still seeing those temps I wanted to install a 60* unit, but never was able to find one in stock when I needed one.

Maybe F.I. up in CO or the engineers back in Germany might have wanted the car to run hotter for their ambient temps. But I can tell you... and sure Dr. Bert can second this, the central valley of California is pretty much a hot plate!
