Well I've done it. Ordered a Power Edge EZ and a AFE air induction system for my stock 1998 1/2 24v. 4x4 w/auto. 42K miles. I pull a 27 ft. 5th. wheel over the mountains in Oregon. Next is gauges (I've been good Santa). What jumper settings do you reccomend? Any other help you can give me would be appreciated.
