the stall in the automatic trans
is 2500rpm. you can only really get to about to MAYBE 2100 before the wheels start turning over and thats pushing it. I dont think he'll be running anywhere near 13.3 with those stock gears. BUT, I hope I'm wrong
If you insist on brakestanding to launch, id start at about 1500rpm then go up incrementally to 2000rpm. Id try idle, 1500, 1800, 2000rpm launches until you find what works for you.
