    DFW Newb-- 2011 Yukon XL 2500

    Certainly an option-- I scored a chipped GT series from PCM and their triple relay. Would need to get ECM 'relearned' I guess but I do have the E38 it would appear. What are the draw backs?

    I don't have the codes on hand but it was done at the dealer b/c this has been an ongoing issue since purchase (from dealer).

    Lifts for 2500 Subs or Yukon XLs...what am I missing?
