Looking For Some info.....
Posted same question on Expedition forum and not getting many responses..I am a proud owner of a 98 Expy with 4.6 4x4..I have previously installed Manga flow cat back system..K&N cold air induction System and still looking for more power..The vechicle sits on BF Goodrich 285's....Seems the calibration of speedo has been off since installing the tires...Looking for any input into installing chips or reprogramming???? Anyone out there whos installed please feel free to respond.....Thanks..Jim
