Ted was super responsive and had me all remote tuned and ready to rip in around 2 weeks. The car is an absolute beast to drive now, I've daily driven it for around 4k miles and I love it even more!
My question is about the heat, which is now a larger factor being SC, and I'm wondering has anyone creatively come up with ways to tackle it in general. During the summer months of 100° temps, I'm seeing IAT/IAT2 temps quickly and easily climb to 140, 150, 160, and sometimes beyond. Mostly when in stop and go traffic of course, but even on the highways at 50-55mph they won't calm down much below 130-140. Also aggravated to some degree with the IAT temp (should be right after the CAI?), which won't cool off much of the time because I can't open the throttle past about 5% without losing traction on the street. Terrible problem to have, I know. LOL
The Maggie intercooler is large and fully capable, however I went to the drag strip recently and sat in the staging line for what seemed like forever before making a couple runs that night. 90+ deg. temps, and IATs would both get to 165-170+ before I was up for a 1/4 mile run. Out of desperation while waiting in line, I would set my fan and coolant pump to run using the Aeroforce gauge @ 19% (which is max setting available), but that did very little to help prior to race time.
I'm thinking of either adding a Lingenfelter 2.5gal aux. tank, and/or installing a custom fan assembly in front of the IC unit up front. Has anyone attempted something like this, outside of the typical interchiller setup? I'm not interested in tapping into the A/C unit and going that route, and also I'm aware of the typical trunk mounted ice tanks available as well. Just looking for alternate ways to fight the heat aside from moving to the north pole.
I'd love to hear ideas, positive or negative or whatever, especially from those creative engineering types out there. The heat soak is insane, and I'm even wondering how to extract heat from the engine bay when I park in my garage! Seems as if my poor RotoFab Big Gulp is just getting heat soaked as well, and can't even function remotely as a CAI. Any help or suggestions would be great, as I'm beyond tired of searching for ideas and need to calm my extreme OCD here.

I believe with the SS kits, IAT 2 is what you'll want to look at and the sensor itself should be inserted in the front or the back of the blower. In the case of a ZL1, there is an IAT3 or Manifold Air Temp sensor, and that is what the computer references to determine if it should pull timing from the car at higher temps.
The real solution (outside of an IC), is to add more fluid capacity to the cooling system. You can do a non-trunk tank option and it'll help some, but they are typically under the hood or close to the source of the heat. As a frame of reference, with a 6 gallon trunk tank (no ice just water) and upgraded pump, I cruise around at a max of 30 degrees above ambient. At the drag strip on a 95 degree day, I will end the pass at ambient starting with minimal ice in the tank and running bottom 8's. If it's iced down really good and I'm not waiting in line long, it'll be a couple degrees under ambient.
