I`m making between 5.0 and 4.9 sec from 0-60, I live at 1607 ft. level, do you guys think this is ok, or my jeep is a little asleep ?? my only mod is a AIRAID intake

Those times are normal. Are you shifting manually, autostick? Try using both ways to see results. I've timed myself at 5.0-4.7-and 4.5. What are you using to time yourself?

live4skins: a nextel chronometer maybe it is not pretty accurate, but by your comment i think i´m doing well, i was shifting auto
