smoke after dual mbc install

[rayrayx11]

my car was running fine before. i installed a dejon dual mbc. made sure all the lines were on tight by either zip ties or clamps. made sure the switched worked before turning on the car. started it up. seemed fine. let it warm up for 10 15 min. (it was about 10 degrees last night) everything looked right. then i rev up the engine a little. i hear a whistle from something. and im getting a good amount of smoke out the exhaust. i know its cold but its never smoked this much before. what happen?!?!

the pressure source is coming from the turbo compressor. and the other line goes to the waste gate.

I'm assuming that the "smoke" was just for that fact that its cold outside. My car does the same thing and The whistle was your turbo. I wouldn't be too concerned
