Default new injectors

If my truck is not plugged in it will blow blue smoke after I crank it. Even after on 3 hours of sitting if its cold enough it will blow blue smoke. Do I need new injectors and if so what are the biggest ones I can run on a stock turbo, I do to a skid steer from time to time.

I have gauges, denny t stage 1 fuel pin, 3200 rpm spring, and the pumped turned up

Mine used to do that. I've been told it's kinda normal for these. If I come home drunk I opt not to mess with electricity (I forget to plug it in) and in the mornig (early afternoon) it will run pretty rough for a while. Oh wells I don't have neighbors, yours gotta love havin that pipe poundin at their wall in the morning, back it in and aim it at you bro, courtesy

Little blue in the morning is nothing to worry about, but if you havn't ran the valves in some time it couldn't hurt.
