leave the gears alone for now
3500rpm + stall converter for your next modification

Get a real tune.. HPP's are junk. Had a buddy that gained .1 in the 1/4 with dynatech headers and and an HPP. Then he got smart and had a basic tune done at speed inc and and knocked off .3. the difference was night and day.

Ditch the tuner.
Get LS1-edit or HP Tuners/EFI Live.
Match up your stall speed correctly.
NEcessary bolt ons and good tune will go a long way.

i was wonderign the same with headers if i am going to lose some low end.. I have TD, with an x pipe and i knwo i lost a little low end. i drove my buddies 02 z with Kooks LTs + O/R H + 1 chmaber flows and his car was beefy under the curve.. Remember i am on stock manifolds for now until i get my QTPs in.. so will i gain some low end back with the LTs??
