not sure but I think you can only reflash to a certain point before you have to go stand alone. Motec, haltec,race-pak and the Holley Commander 950 will all work though. Motec is the best money can buy but its spencive. hit up CHRFab.com they sell the holley rail kit for 1725, might work for you. whats it goin int btw? I thought bout putting a n* in my 99 ranger.
