injector problems??

[Glasseater]

ok this has got me pretty curious... my friend's brother just bought a 2002 f350 with like a small 4 inch lift and 35's on it, with... dum dum dum!! a banks kit in it lol i think it's the 6gun, not really sure seeing how i never actually got to look inside the truck... anyways so his brother swears he has an injector problem cause his truck "smokes black on anything more than half-throttle"... now i'm thinkin that if he had injector problems it would be more of a blueish or white smoke?? now idk cause i have no idea about anything about injectors but i've followed him while he's driving and at this half-throttle it only smokes slightly more than my dad's '02 excursion... which is completely stock... maybe he just doesn't know what real smoke is?? thanks guys for any input

Ususaly black smoke is an indication the motor isn't getting enough air for the volume of fuel it is trying to burn. That being said it could be the chip or a clogged air filter causing the smoke, if the filter is clean and the truck runs smooth with lots of power it's nothing to be worried about.

yeah i'm pretty sure it runs smooth, this is his first diesel so i'm guessing he's just worried that he sees any type of smoke at all... it really isn't THAT much.. it's like a slight haze at half-throttle

None the less have him check the air filter just to be sure.
