OK. I just got my idle fixed on my talon, was a hose missing. ONce idle was evened out, I turned it down to about 1k with the screw on my throttle body. I also got the exhaust shop to put a side exit exhaust on my car just the other day. NOw, I noticed when I am sitting still, if I rev it to about 2500 or 3k it will smoke out the exhaust. Then today, my brother was driving it and I was following him, and I noticed when he was coming up to stops and he was downshifting, as he was slowing down, it was smoking out the exhaust a fairly good amount. I have never seen it do this until I fixed the idle and got the exhaust done, on the same day. He got on it once, and it puffed some out when he shifted from 2nd to 3rd. The smoke looks kinda blueish mabey, hard to say. From behind him, I couldnt smell burning oil. When he was revving it up and I was beside the car, it smelled like gas really badly, does this sound like my turbo, or is it running rich for some reason? I checked compression in it about 3 weeks ago, was 150 across the board. Have only been running around 11psi on aftermarket guage, and try not to rev it past 5500.

oh yeh, forgot to mention, the smoke doesnt look really thick.

smoke looks just like the smoke in this video, but it doesnt do it idleing, just does it when it is revved or when slowing down. I also noticed that when slowing down, it pops thru the side pipe kinda alot.

Thanks for help in advance.

At 11 psi you are probably just running rich. Do you have a cat or anything like that? I would pull some IC piping just in case and check for oil and shaftplay. Doesn't sound like a turbo problem though.
 
I have a 3"dp and 3"test pipe to a 2.5" exhaust with side exit and no muffler, them are my only mods.
Thanks for help so far.
 
I will have to pull the IC pipe and check it tomorrow, my brother is driving it to work tonight, he works 3rd shift.

video of it. I cranked it and let it idle to operating temp. The liquid under the pipe is water, it is freakin cold outside so there was some condensation. IT is actually a little hard to see the smoke because how brite it is outside, you can see it as it idles down coming from the pipe.
