Gear ratio and tire height for DD stock 5.3L / 76mm turbo combo

Wondering what rear gear and tire height you guys have experimented on your mild turbo 5.3 setups? I currently have 3.42 gears and stock 30" 265/70/17 tires.

60E or 80E?

I have 4.10's, 30" tires, and 80E in my turbo 5.3 truck, but it's not a daily driver. If it was, I'd want 3.73's in the rear.

80E. Maybe I should keep the 3.42s and run a slightly smaller tire?
