With the 4 speed I liked my shift points turned up a little. You want your shift points around 200 rpm past your peak power. This lets you hit the peak power while spinning the RPM up a little higher to aid in the rpm drop between shifts. I ran my 08 5.3 RCSB at 6100, 6200, 6200. Full bolt ons, tune, nitrous. No cam, no stall.
