Default 4.8 mods so far

Got my tune in, and it drove like a completely different truck. Got rid of almost all the DBW lag, and all around crappy throttle response. This weekend I put the long tubes on and WOW. They made a little difference on my 00 with my cammed 6.0, but man, this 4.8 really responded well to the change
