UPDATE: Car seems fixed!!!

OK, car seems to be at 100% now. The dealership had a wait what seems like 2 weeks for them to get a new style fitting from GM in order for them to properly do a Bleed of the Cooling system. Apparently there must have been air in mine that wasn't allowing the coolant to circulate through the supercharger intercoolers and thus why my car would fall on it's face 3rd & 4th gear on the track as the ECU as just pulling a bunch of timing to protect the motor.

For those that care prior to getting the car back i took some temps of the Intake plenum and the read out would be 165ish degrees across the plenum(once at full operating temperature).

Now the car reads 126ish degrees. This was using a Laser Temp gun that I use for tire temps at track.

Upper radiator hose read 175 both before and after and the lower also had the same readouts. So it all seems to have been an issue in the charge cooling system that is now resolved.

What's funny or sad is 1st & 2nd gear doesn't feel much different on the street as it doesn't hook anyway but what a difference up-top. I remember being very underwhelmed when I first took ownership but figured I had gotten used to faster cars I've owned. But once I got it out on the track and it was well under the MPH speed it should be hitting on the straights I knew something was up.

Now I can't wait to get it back on the track for some true tests.
