5500 is all you will need until you go with other performance mods.

 

well i got my edge in and set it on level 2 it does pretty good i dont think the rpms on it are right at about 3500 3600 on the edge it sounds like its bout to blow up which i dont know if changing the tire size helps out i got a lil bigger tires on my truck im waiting to drain my first tank of gas to get 93octane to put it on level 3 and see how it does
