Not to beat a dead horse but WTF over ???? No programmers just BS Jet chip. I would pony up 400 dollars for 25-30 real world horsepower and firmer shifts. I didfor my F150 and thensold it used for 275. Other than intake and exhaust, which are good starting points but not complete without a programer, theres nothing....Too bad.

 

SCT has support now for the '04 4.7, at least I know there was a group by on another forum for them. Air Ram swears by his SCT on his 4.7...
