Also to add to my post, someone please correct if wrong, but I only think there is roughly a 4% difference between SAE and STD. Dyno was 72 this day. So 4% lower puts it right were 10 speeds should be between 385-400. Also, this was only a 6th gear pull instead of he standard 7th for 10-speeds as in 7th we kept hitting speed governor as the 2020 LT1s are limited to 150 due to all season 245s.
