I have a 97 5.2. Just did the throttle body mod last week and put my exhaust on yesterday( flow tech headers, flowmaster scavenger y-merge to 3" straight through magnaflow and then straight 3" to axle). Made a pretty noticeable difference in power, sound is awesome. I plan to freshen everything up In the engine in the sPring. .20 over, cam, port the intake and maybe even aluminum heads. What are my tuning options? All the programmers are for 98 and up, what's the difference?
