WI For Jetta TDI

[dlai]

I've haven't seen this posted before so I thought I'd post. I have a 2001 Jetta TDI. It's highly modded as far as TDIs go. I have upgraded the injectors (PP502, for those who are interested), and the full Upsolute Stage 3 kit (GT20 turbo, bigger manifold, FMIC, custom s/w). The car smokes more than I would like and I would like to tone the smoke down and also benefit from the addition of WI. Would adding a WI system help with my smoke, will I gain additional power, and if I do install this, is it better to install pre or post turbo?

Thanks for your input.
