just bought a 08 rcsb 5.3l w/3.73, went 2wd this time instead of 4wd like my last truck. i miss my old but love my new one, took all the nitrous off the old truck and im waiting to put it on the new one. i was looking at slp's web site for package deals but didnt see anything for the 08 body trucks yet. im thinking cam exhaust tune etc, you know the good **** for a new truck, plus the bottle. i got a ways to go to make it look right though. ill post new pics soon but i need help finding out about eng. packages, if anyone could let me know somthin i would really appreciate it.
