I need help with what stall speed to run with my 02 silverado 5.3l 2wd. i have been looking yank brand 2800, 3000, and 3200, but i dont know what speed though. I do plan to have a supercharger in the near future but for now this is what i have:

Volant air kit with scoop
Corsa Exh
GMS Mass Air flow sensor
Hypertech prgrammer
ASP Gen Pulley
