Can some one tell me how you can setup the speedo gauge of a 99 alero ? because normaly the car came automatic but I swap it with a manual gearbox. So the question is how do I change the VSS pulse in the hp tuner ? Or what else do I need to calibrate to make the mph accurate

this is my car, and playing with speedometer setting on hptuners, found out that my stock tire/gear value is 8.22, but when I do the calculation, it gives me 8.50 (26.2/3.08).
can someone tell me if I'm wrong, or what do I have to do?
