How to pick AR for 1000+ twin turbo 4v?

I will also be running a Sullivan lower with an 90 elbow, possibly a Wilson or a 6061.

PTE makes the 6466 turbos in a .68 and .81 AR or divided in a .84 AR.

i thought turbos like longer gear ratios for the load and with an auto once you shift to 2nd wouldn't the power be different since the turbos are already spooled and don't loose boost as compared with a stick?

I run a 3.25 rear gear, it's more gear than my trap speed but the car performs much better with the 3.25 over anything higher.
