Hot starts with FAST 90/90 (Corvette) ? Ok, I have the car running very well no hanging throttle no bouncing idle drives like a dream.
BUT I can't get the hot start squared away, it starts revs up and then dumps down to 600 rpm or less bounces around and dies unless I keep it running for a few seconds and then its all good.
What am I missing here all the things that worked when it had the stock TB don't seem to fix it ? Please help...

Try leaning out your Cranking VE by same percentage as current VE vs stock VE.
If Current Main VE is 70% of stock Main VE at idle then reduce the Cranking VE to 70% of stock Cranking VE. Too much fuel at startup was my problem with warm starts - leaned it out and it's cured. 2001 C5 239/251, 106. FWIW.
