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

Getting antsy to do "something"... mechanically it's done till steering gets replaced/upgraded, power is done till its paid off and I contemplate super or turbo, still waiting for powerfold tows...

So thinking of trying a slight appearance mod to go with the "MTB" theme. Something like this on the bottom of the rear side windows??

The heartbeat one is cool.

Are you satisfied with the Black Bear tune? Did they tweak the shifting?

The BB tune is night & day from stock. I hate myself for not using them on my last two GM trucks... wasting money on handhelds.

Shifting is spot on as well. Stock settings would shift too early and the truck would fall flat on its face at around 60mph while trying to get up to speed on the highway. Now it keeps pulling HARD through ~90, and probably further but I haven't gone further

I might have to look into this!

Not much has changed.... but been a good 2 days. Tire rotation, oil change, greased joints, and a quick wash today

Will be putting her to use soon. Closing on a house at the end of the 29th and looking for a nice enclosed trailer to help with moving

Used every little bit of the lift/tires/gears today. Truck was loaded down with trail maintenance equipment and we had to get deep into the woods for the planned work. The rangers forgot to unlock the gate to the access road, so we had to take a "detour" up and around a powerline path that's long, steep, and loaded with sugar sand. The only thing I didnt do was air down, so I didnt make it up the steepest sections (of course i tried the hard lines first ). In the end we got there, and 4-low with the 6L90E and 4.56s feels like it can rip a house down!!

Only regret is not getting out and having my son stand in the ruts that were up to his knees. If we dont get any rain I'll head out on Tuesday with my bike to document the shenanigans

So it is a 4x4. I think that's the first time you've mentioned that fact in this thread.
