i have a 99 ps. turned my tuner off and im getting real light grey smoke when i put a load on it. i checked my oil and coolent level and its all good. leaking injector or?

 

How many miles on the truck? What mods?

Does the smoke have an odor?

Doubt its an injector, sounds more like a turbo issue...

 

cts programmer, banks actuator, afe intake, 4indp, 5instacks
if i rev it up it will poof grey smoke, if i put it under a load driving it will smoke. 80 thousand miles on it and isnt running bad or making any weird noises.

 

Gray could be blue or white??? I would pull the turbo intake and see how much play is in it...
