Superchips Power Programmer Flashpaq Questions
I have a 2003 XLT 4.0L. I was thinking about getting one of these babies. I really only want to remove the speed limiter but apparently it can do much more. Does anybody have any experience using these. I really want to get it but at the same time in the back of my mind I think it's going to **** with up the truck by messing with it's factory settings. Let me know what you guys think. I can get one used that he only used once in back in may and he still has the receipt for it.
