use 0 for driving around town. 3 for racing. i never used anything in between. 0 is low boost, 1 is medium boost, 2 is high boost with stock tires, 3 is high boost with high traction tires.
Sorry for the noob question but could not find this answer in "how-to" or anywhere for that matter. Going to be installing S2 soon and I have the N2MB toybox. How exactly do you set DAB? I have an AGP WGA so do you just set it so say 20-21psi for s2 on the wga and that defaults as DAB 3? If not what do I need to do to set it exactly?
