    Looking good so far!!!

    I bet that 4.8 doesn't like those big tires on the freeway, unless you are lucky to have 3.73's.

    I just saw your other post about the gearing, I kinda knew you weren't going to be happy lol!! What gears do you have now 3.42??? I had 35's and 4.10's on my 05 silverado with the 5.3 and it was a dog. I bumped up to a 4.88 front and rear gearing and it was a lot better, If you go to a 4.10 it will be even worse on gas, but you will get some power back. Big tires are a double edge sword, they look bad a$$, but boy you pay the price!!

    I believe inside your glove box, there should be a big white label on the lid. It has a list of all the RPO codes, I am not sure which one's they use now for gearing. I know some of the older one's had like GU6, G80, G86 and so on. Maybe someone with a newer truck can answer that one, I haven't bought a new truck since 05'
