Help, Idk Why I Have Smoke

[imported_RST531]

Ok, well my car smokes, well is ok well im doing reg. driving. But when i drive it hard i see smoke from my rearview mirror, but i figure its not that bad. But last night i was racing against 2 SIs (03 & 04) and also a friend tailing behind us. Well after we raced my buddy was telling me that i had lots of smoke coming from my car (dark smoke) and lots of it, i didnt know it was that noticeable, but idk what the hell it is. Anyone know if their might be a problem with the car or is that just the way it is. Car info is in the Garage.

is it blueish white/gray or grayish black.. oild or coolant is being burned depending on the color could be a few diff things.. check your lines for coolant and for head gasket wear

From what my friend described its more of a dark grey color. I've had my ecu chip'd with a skunk2 chip, would that have caused the smoke.

Also can someone post the changes the skunk2 chip does, i cant seem to remember, i know the speed gov. is gone or atleast not at 120 anymore.

might be running really rich on hard excel.
time for a dyno tune

Dyno Tuned that sounds like fun, Ive never had one yet.

The skunk2 chip is probably your problem, it's on the rich side of things. Dark smoke = running rich.

So is there a way to tune it so it wont do that, or would i need to get a new chip or something else.

rich. dark = unburned fuel.

My friend had a blown head gasket, and he was burning so much oil it was carzy. We took the engine out of his car and his cylinders were half full of oil, he had to do a total rebuild of the motor. Does your car seem to be a hell of a lot slower than it used to be? If so I would say that is your problem.
