Duramax Third Generation: 2006-2007.5 (LBZ & LLY)
I have an 06 LBZ with a built motor that is bore 20 over with a fleece 68mm with a wicked diesel cp3 upgrade and 45 over injector nozzles and Idaho robs tune. Every time I start it up it blows a puff of white smoke and if I leave it in a higher tune the worse the smoke is. Is this bad, alright...
