There are guys on FTE.com that have done it, and from what I know they havent had an issue. I am not familiar with these white stars you are talking about?? I am familiar with FCDP up in Jacksonville. I like his EGR delete kit, but its little expensive being all that it is, which is just a welded intake manifold (closed off EGR). I cant see paying 600.00 just for that. Oh, and its powdercoated. There are guys running full delete kits with new oil coolers that are 500.00 total. Anyway, I dont know if they guy took my advice on who to go to, I personally already will just do the work myself after my ESP expires. I have rebuilt plenty of motors but this being my first diesel, i see it as a challenge and welcome it as such.
