I've only had my Tahoe for a short; that being said I've read a lot. The BLackBear tune is highly recommended. No down time, just core charges, and security deposit. EFI live is far superior to a handheld run of the mill tuner.
if your keeping the 6.0 stock your stock4l60e will hold up for a while.if you can swing the extra money have a transgo hd2 shiftkit put in with a vette servo.should be alot cheaper than the 4l80 trans from the 6.0.and you still need other parts to get the 4l80 in your truck.oh also do atrans cooler with the shiftkit.if you do these upgrades amd in your bb tune they can tune out some of the torque management and the truck will be an animal
