Mishimoto also has a coolant additive : Mishimoto Liquid Chill® Radiator Coolant AdditiveThat's a really good idea, both redline and Lubegard have coolant additives shown to reduce coolant tempts.
Obviously once the super is on there I'll be driving with my Torque app showing coolant and transmission Temps like all the time to start with, and every time I'm on track. Be data driven about whether or not heat is an issue.
Also thinking it would be great to add oil pressure and temperature gauges when adding the oil cooler...
