Hi all, my first post here looking for help to my smoking problem. I just bought a 2006 5.9 1 ton a few months ago and recently it's been letting out a puff of white smoke and idling rough in the mornings. Smoke only lasts a few seconds and the rough idle only lasts maybe 10. Usually accompanied by 5 or 6 cranks before it will start. Everything I'm reading is pointing towards injectors but they were just replaced less than 10k miles ago with industrial injections 75 hp injectors. Is it possible an injector has gone bad already or am I missing something? Any and all help is much appreciated.

The truck is moderately modified, it's got a fresh rebuild on the engine, 75 hp injectors, efi live 5 stage tuning (stock, 40 hp, 70hp, 90hp, 120hp), aem cold air intake, batmowheel billit compressor wheel, 2 piece bd exhaust manifold, s&b intake horn, arp head studs, 110 lb valve springs, 5" turbo back exhaust and a fass 150 lift pump.
