Performance Gains With The Superchips Flashpaq F5 Performance Tuner On A 1999 Ford F-250 5.4L

Published 10/06/2021

Question:

I own a 1999 Ford F-250 Super Duty with the 5.4L 2valve engine. I’m interested in the Performance setting and the Heavy Tow setting. I already use 91 octane gas only. How much gain cam can I expect in the Performance setting and the Heavy Tow setting?
