I've been wondering this for a while...I have '06 1500 4wd & girlfriend has '03 1500 Z71, same 5.3 V8 in both, both have over 125k. Mine is much more sluggish off the start, why is that?? She hasn't done anything special to hers at all but it just has a different faster, lighter feel to it when accelerating, what gives?!
Mine was bought here in Colorado, hers was bought in Michigan, could mine have been tweaked somehow with different factory settings for higher altitude?? How can I get mine to be a little more zippy??!!
