I don't expect a lot from this, but hey, it's worth a shot and its a simple, passive mod.

I have no experience with the LT1 or the new Edelbrock's for it but I have several LS3 customers only use the TMAP for MAP and relocate the IAT by using GM compatible sensor with GM scaling in tune. This resulted in much lower real temperatures since the TMAP was boxed in and reading housing. I know you have to be especially careful fooling with IAT, you dont want to make changes if you are using a canned tune.
I would check Intercooler coolant temperature against IAT in real time. I always watch coolant temperature a display is included with the Chiller kit. The AU SS I'm working on now has a flow gauge and 2 temp displays. That's another thing, you have to have all the air out of system the flow gauge picks up air in system great! I had not seen these displays and think I will add them as an upgrade to my old faithful.
