So the unit above is all stock ecxept the deletes and tune and stock injectors, it started off white alittle unburnt fuel at start up and has gotten worse, where on cold start up the truck idl e rolls once or twice and then is good but still the smoke. The injectors have been tested and all passed, the dealer said thier was no return fuel out of the head to the tank which lead me to belive bad injector but that was ruled out. truck was put back to stock minuse the exhaust and still have smoke, tuner said then its not their tune. what else do i need to look at truck has 3500 miles on it.

Thanks

Matt
