Gear Vendor and 833

My combo is a little different. Current 833 has 3.09 first and 1.1 4th. My rear gear is 2.94 with an Eaton Tru Trac. The sb makes 505hp at 5700 and 526tq at 4300. I don’t have a tack and shift by mph. 50, 80, 110. 3,000 rpm is 78 mph. For me, that’s not quite comfortable cruising.
For me, the whole deal is based on shifter position which doesn’t seem to be a problem. The cost is a little high, but some searching around may yield some savings.
