Up date. Well at about 1500 miles now, and still very happy. Nail the gas from a dead stop and the truck puts you back in the seat. No real wheel spin from a dead stop in a straight line. Just jumps to attention and goes. If you do brake the tires loose, both sides will spin as they should. Its a lot of fun on wet roads, or if you nail it around the corner from a dead stop, it will spin the tires. As most of yall already know, a week and a half after the install, I blew the sunshell, so I had to rebuild the trans also. A HD rebuild kit, corvette servos, and a shift kit. So the total cost for both was almost $4000. $2800 for the trans, and $1100 for the diff. But hey now my truck will last for many years to come. At this point, everything mechanical on the truck is not more than 3 or 4 years old except for the internals of rhe engine.
