This is the one ive been looking at. https://www.siliconeintakes.com/front-mount-intercooler/water-to-air-intercoolers-p-213.html
I believe i have room on the intake side right by the strut tower to sneak it in .
I'm not doubting that its working well. And the fact that your not seeing those spikes is due to the thermal mass of the intercooler and antifreeze thats in it soaking up the heat from the charge temp. I guess my thinking is when is a colder IAT not a good thing? And what are you trying to avoid by having it run all the time? If its noisy and it bugs you. Sure, I can understand that. Its only pulling a few amps and I just dont see a downside other than maybe noise from the pump. With that said. Ill leave you alone to your decision. I dont run megasquirt currently but it seems that the simple way would be on off with a relay that you could tie into which ever data point you want. There isnt going to be one right answer for this. When autocrossing I would want it on 100% of the time.
On your turbo setup. How do you like that turbo? When does boost come in? That turbo has been on my radar for the future. Im not looking for a hp monster any more. I want 300 ish hp to the wheels on my wagon. Its a cruiser not a drag car! What i want is power lower in the rpm range. I wont be getting the protunerz manifolds. while nice i know i just wont spend the money on them. But I may be convinced to go away from my 2nd hand cheapskate tendencies to get a nice turbo for once.
