Well guys and gals. Im Aaron from AZ. New to DD but not so new to diesels. Hoping to learn more as we go here. Seems like you have a great group of members that are knowledgeable in the Diesel performance world. I own a 04 cc sb 4wd LB7 it has st8 4" exhaust, intake,ppe bv, 3.5" turbo horn , Efi Live dsp5, edge CTS , that's about it performance wise. Looking at twins and SC IV in future. Hope I can help be part of this Diesel community.
