cold start or injectors

[speedmetal6.6]

It seems lately or else I didnt notice before , my truck puffs a little white smoke out after start up and it puffs a little more until the high idle kicks in and then it stops, also it doesnt do it when the truck is on the stock setting What could be causing this? Is it because of the Hot tune its on or what ?
