Smoke from exhaust on deacceleration/accel?

[dro]

Whats this mean? I can't really tell if its on accel or deaccel. Maybe i am worried about nothing but when i did my cam swap none of my plugs were coated in oil, they were all a nice brown. My coolant is not brown nor does it have oil deposits in it. Is it just because its a modded motor or what? Ive never really noticed any other mustangs that smoke as much so im semi-kind of worried.

EDIT: Mods are:

Steeda 19
Full exhaust
no smog pump
no egr

really only mods that should matter...

i wouldnt be to worried if it was a gray smoke but blue or alot of white could indicate a problem... if its gray its probably just carbon build up in the combustion chamber.

what color smoke and does it have a smell have a friend drive behind you and tell you when it happens and the smell. any smoke isn't really a good thing but some colors is worse than others. did you get a tune after the cam swap?

sure did, and my GF when she rides behind me calls it 'white smoke' but i know how far that goes because my GF doesnt know much about cars. As far as the smell i made her describe the smell and its just the normal exhaust smell like you would get from an O/R midpipe. I honestly just noticed it when i got my car tuned and just thought i would look into it. If it does need a ring job ill just go ahead with a 331 but i guess a compression test will tell me that. The car only has 110k on it.

can you smell anything or see any smoke at idle and when you rev the throttle

If its when you decelerate, and it also happens when you start the car (blueish smoke) , it could be bad valve seals.

Nah it happens when i am wide open acceleration. But normal cruising no smoke what so ever.

Dont get me wrong though, the other morning i crunk it up when i was loading my tools and such in the truck and it had kinda puffy white smoke but i think thats because i havent cranked it in about a week, lol.

yea next week im going to get a compression tester from a buddy of mine and doing that to see whats up. If so, ill just stroke the SOB.

as you may know white smoke=coolant, blake=fuel, blue=oil, good luck
