Gray smoke??

[GReeves]

Hey guys, while getting on to the interstate today i punched on the throttle to beat a car that wouldnt let me in....noticed that my exhaust was not solid black like it normally is when i hammer on it, but had more of a gray tint to it. Is this indicating a problem?? No error messages, truck runs good, it is time for me to change the oil but other than that truck is running like it always has. My truck is a 2015 de-leeted using SCT X4 with PIP V-7 tunes running it on the Performance tune, 38,000 miles on it....any tips or help is greatly appreciated! Thanks

Mine does that sometimes when I just flat foot it to the floor. Running h&s mini max.

Could be the way the light is hitting your "coal"

It's the way the sunshine is hitting the soot... Trust me

Cool, thanks for the replies. I turned it back down to the street tune anyway, hardly any smoke even when i mash on it. Another question for you knowledgeable folks, does anyone know the horsepower gains with each setting on PIP v7 tunes? Id like to know what each setting is HP-wise. I have Tow, Street, Performance, and Extreme on my tuner.
