Jetting

it just bombs around town most of the year but the real problems show up after/during my annual cross country blast to moparfest ,3000miles / 5000km one way equals about 45 hrs of highway over about 4 days depending on traffic . Brian sent it to me with 6.5's front and back for power valves I swapped them for 4.5 's a couple of year ago when it was loading up at the lights around town .
