Ford SVT Lightning chip question
I bought a 2001 Lightning last week, I'm still learning this truck so I need some help. I was told that it has a pulley upgrade as the only mod. The boost gauge jumps very quickly to or past 10. I have feeling that this is not a good thing. How do I tell if the pulleys were changed? And ho aggresive of a change. Also, I have read about performance chip upgrades, how do I find out if and what type of chip was installed. I realize these are dumb questions to most of you but I am playing catch up since this is 1st Ford since my '02 Mustang GT. I love the truck btw, it really moves.
