If I had to buy one I would definately upgrade. Since my buddy has a couple of backup G80 units, I am just going back with the G80 for now. It is going to the trans shop for servos and a converter on wednesday. Then back to the tuner. So that is my allowance for this month on the truck, LOL. More than anything I had not serviced the rearend yet, it only had a couple ounces of oil in it. LS1 and 20's are not a good combo for the Gov Bomb. am not usually the type to cheap out but I still havent decided on what gear I am going to run so I will do it right when I install a Tru-Trac.
