This is with a mild AccessPort Drive tune on an N54, so any hotter tune would further accentuate the problem. Oil temps are fine. The engine is still coolant challenged on this track (which admittedly is a tough one on cooling).

I am thinking you'd get better results if you coupled the CSF radiator with the tuning revisions to target lower coolant temps. Definitely move to straight water if you haven't already.
I will say that Limerock Park is not particularly taxing on the cooling system. I'd probably have much higher temps on a track like NJMP lightening (lots more on throttle driving).
