68 camaro supercharged 5.3 idle problem

[EagleMark]

it was running 230 degrees before now about 120 but it just wants to die out when i let off it fast

I had no idea SC made that much heat! Almost 50% reduction in IAT is huge!

I know the tune is more important and your lucky to have Buzz helping, but if you have a picture I'd like to see the setup...
