| welcome to the site...i sold all my Duramax's for sevaral reasons and i even offered to step down from my position as a mod since i'm in the processes of building a 12V and no longer have a Duramax but i my father and 2 brothers and have Duramax's so i do all their tuning for them so i'm still around them everyday..
just a word of caution,the LLY has been known to overheat so i would upgrade some cooling stuff to avoid that from happening..contact killerbee(Micheal)he has done quite a bit of research on what causes the overheating and has some upgrades you can do to avoid that from happening to your Duramax.
other upgrades are
Exhaust=Silverline or MBRP.
Programmers=Diablo,Quadzilla,ATS,PPE or EFILive.
CAI=AFE,AEM or Volant..
