I understand what an intercooler does and why you'd need one with a turbo as the turbo heat soaks the intake charge. Cooling cold air seems futile to me lol.

That is just it - the air stream coming out of a supercharger is not as cool as the air going into it. Ever notice how the 80 gallon tank on the compressor in your shop can get very hot to the touch when using multiple air tools ? It is not soaking up any heat from anything - mechanically compressing air causes its temperature to increase.

it was running 230 degrees before now about 120 but it just wants to die out when i let off it fast
My apologies for the thermodynamic sidetrack ....
That is a good reduction in temperature. Where are the MAF and IAT located in the air stream ? Also, you never posted a tune ... what are you running the the 5.3L with ? PCM, E38, E67 ?
no maf the iat is after the cooler right before the intake
I took a very quick look at your tune. You are running an EFILive COS3 OS. Do you have a WBO ? How have you been tuning thus far ? It appears as if the Boost VE table has not been refined beyond the initial setup.
Can you post a log of the stall event ?
You may get more hands-on support with this if you were to post on the EFILive forum.

That is quite the project. Did that start out as a manifold mounted supercharger?
At any rate, why is the throttle body before the supercharger? All the air volume between the throttle body and the engine will really mess with your throttle response.
Sexy!
Before the cooler did the air run right in front of the radiator? Just wondering how much of that temp drop was compressed air and how much radiator heat?
