Welcome to the forums! Im having the same problem bro; a n/a stock Series III 3800 and nothing to do to it but mods around the $900 range. They make cold air intakes for our cars and theres some stuff on ZZP that will work on our cars. Ive also been told that some of the mods for the Series II 3800(L67) can be interchangeable to work on the Series III as well, but havent tried it myself to find out. check out 3800performance.com as well, they have a few products for the Series III. No mods for our engine are cheap, just fyi. Good luck!
