    If u havnt seen my last post a week ago I put together a c15 mbn with a 6nz platium kit pdi turbo a 7cz file and a 800 hp marine cam. Now I got the truck running again after changing another cylinder pack I got about 1000 mile on it and the whole time when I let it get over 30 pound of boost has a fluttering sound coming out of the exhaust as long as I keep it 30 and below it sounds fine anyone got any suggestion? Thanks

    You're not havin much luck with this thing so far. Did you get around to matching the trim codes in the ecm with the codes off the injectors? I'm just getting mine all back together after a total rebuild, and I plan on getting that done very soon.
