Unplugging the battery for about an hour so the computer can readjust to mods? I've heard of people doing it but unsure if it works.

Also what do you guys thing i am am putting down on the dyno and ion the qtr mile with my current mods?

 

Looking at your sig i see no need to do anything to your computer.
Recalibrate your spedo for the 3:73 gear if you have not already done so.
