smoke at WOT, 4x4 question
 

so when i put my chip at stock setting and i get in the peddle i see smoke at WOT, but its not black smoke, but like grey. and even when i do have the chip on a tuned setting, usually 80H economy setting. when i step on the peddle i dont get a good black smoke like i see everyone else get. i get like a blackish brown and its not to thick or anything like i see from other trucks. anybody have any ideas?


also, when my truck is in 4x4 if i turn it hops, i forgot if thats normal. i just had front end work done, replaced hub assemblies, and outer shafts.

for the smoke. i'm not sure. thw 4wd, yes. that's normal.

Sometimes if there is a faint amount of smoke the way the sun hits it makes it look whiteish gray.
