Do I need a thermostat?

I've had my new Nissan Motorsports unit all of one week today and I have noticed a dramatic decrease in oil temps but I also have a new short block so I am under break-in with a 4,000 rpm limitation. I saw temps of 245*F during break-in, on my original engine. Now low 200's.
I've read the entire thread and do not think I need a thermostat for my oil cooler, but I will ask. I live in the California bay area that has only snowed half a dozen times in 30+ years, and it does not last on the ground an hour. Temps range generally from high 40's to mid 80's. Do I need a thermostat? Thank you.
