smoke coming from exhaust and through vents upon deceleration

I know one of the turbo seals is a little leaky and that would explain the smoke coming through the exhaust and the slight burning smell there, but it has started also coming through the vents. this tells me it's smoking under the hood. would a leaky turbo seal cause this, or do I need to be looking at VCG or OFHG? I know both those gaskets very lightly seep but haven't seen any real leakage.

car is a 2007 335xi n54. mods are DCI, cat delete DPs, and MHD e40 tune.

so you think it's something separate from the leaky turbo? I may go ahead and replace the VCG and OFHG soon just trying to score an oil cooler version since mine doesn't have it before I tackle those
