How's everyone doing? I am new to this site and this is my first post. After having my truck for a lil over a year its time for some changes. I know i'm gonna get a lift, probly the rancho 4". does anyone have experience with this lift? I am also looking into a CAI, throttle body spacer, programmer and headers. Already have flowmaster 40 Ko muffler. What i'm looking for are words of wisdom from anyone that can help. Are the headers and throttle body spacer worth it? If so any specific brand? And i guess the same question would go for the programmer, was looking into the superchips line. Any other advice and knowledge would be great. Thank you and sorry for the essay, just trying to cover some of what i'm trying to do.
