I'm curious on your 4.56 gears and 6L90. What rpm does it run at 70-75? And during normal driving, what is 1st gear like? I've been considering 4.10 gears in my 09 Tahoe L9H. My concern is it will be annoying at highway speeds like my 05 Tahoe with factory 4.10 gears is.... The engine just screaming at 75mph. Currently the 09 has factory 3.42 gears and the 6.2 feels good, but I think the 3.42 holds it back some.

Its great on the highway. Cruising right around 2100 @70, no downshifting on little inclines. I like to keep it 70-75, but its still not screaming at 80. If I wasnt planning on towing (and if they made them for my axle) 4.30s would be good too.

Doesnt feel like a heavy truck while driving. Only issue I found was when I put it in 4low 1st gear is slooooow, but itll pull down a house lol. I was manually shifting and using 2nd gear in 4low
