and this whole re-gear thing, do i do it from the gryphon settings or do i need to open up the rear differential and chance the gears in there?

To regear you have to physically change the axle gears. Then, like 88Racing said, you go into the gryphon settings and put in the new gear ratio so that the pcm will keep the shifts where they need to be. I'm not sure if your gear ratio or something is set right because if your 70 mph rpm sits around 2000 and you have the 3.55 differential then your rolling on 29-30's not 35s.
Is your speedometer/odometer accurate? My truck has stock tires (with about 6.5% squish) and 3.55 LS axle.
But if that is what your getting then just leave the physical gears alone. About 2000 rpm @ 70mph is pretty much stock.
