FMIC is a funniy thing..
The natural ideal is "The Bigger The Better"
That is not the case always.
Average Ambient Temp and How close the the Edge you plan to take the Turbo.
I have the SC FMIC hooked to a GT30 71 and normally it is hardly working, thus hardly making heat.
If I still had my GT28 and was pushing the same HP, I would be worried and want a huge FMIC like I had in the past.
last spring I redid everything at once and carefully planned everything to work together.
My IAT has yet to log over 42 Deg and that was stuck in traffic..
Under load it quickly drops then slowly climbs, as soon as I let off the temp drop.
The SC FMIC was a great addition to my car.,
