slightly off topic, but i have a tendenacy to blip the throttle around 4k rpms with the NPP switch set to open while under a bridge to make some noise... every now and then when i do this, the car revs and seems to backfire... sounds like a 9mm round being fired

Hi all,
Yesterday going to work I had a guy I work with get on my tail to play. So I gunned it. He told me a big amount of smoke came out my back. I was told this same thing by my boss who did the same thing when I left work and gunned it.
What is causing this carbon buildup? I use Exxon 93 gas. Maybe it is time for a change.
Any help would be appreciated.
Thanks,
Steve

My theory from what I have seen is that the carbon gets built up behind the exhaust flap that is closed. So when you nail it and it opens up, it blows it out thus creating the black cloud. I may be completely wrong but it seems reasonable to me.
