Second, the idle is not as rough as my previous setup which makes sense as I had a very large cam and was running about 13.5 to 1 compression with that NA setup.

I noticed more super charger whine when compared to a basically stock 2019 ZL1 that because had since I am spinning the supercharger FASTER. The torque comes on INSTANTLY even though I am being very gentle on the throttle.

AMP has said the engine was set up to make 750 to 850 ft lbs of torque over a very broad RPM range which of course we will confirm in a couple of weeks after Break iN on a DYNO.
Sounds like you nailed it !!! Awesome job !
