Power loss at 215-220 oil temp?!??!

220 sounds too low to trigger a nanny. FSM should have a setpoint value. My guess is that AIT is getting too high. A decent OBD scanner will read AIT.

You are bang on! Had mine on a dyne for 5 days straight and we saw a significant drop in performance when AIT went above 60 (almost 20-30 hp loss).

if your sitting in traffic or city driving the car, you will always be above 70. as hard to believe as it is, in order to keep this motor cool you need to keep it moving.

Even adding an oil cooler will not fix this issue, the engine can only do so much when the temp of the air in the engine bay is so high.

Get an OBDII reader and monitor the intake temp and just like mentioned above, I'm sure you will see the power loss come in after the AIT hit 60 or higher.

Keep in mind this is the AIT that the ECU is reading from the MAFs before the air is cooled inside the manifold. The Stillen is definitely 'heat soak city', but the actual AIT is probably (possibly?) less than that. I'll bet my turbo-compressed air would be a pretty scary temperature too before the IC.
