Friend of mine just ordered a 2012 GMC 3500 cab and chassis to put his utility body on, just found out its rated at 235hp 
can he have it reflashed to the LML os? Also will the H&S mini max work on it? He would just assume go with the LML 2500 OS 397/800 instead of buying the H&S but he wants it to have some snap.
