I use the same box and really no smoke, but at night with cars behind me I see more of a haze in their headlights than I did before I put the box on.

 

I have the va box also,this past summer I ran with dd2s and boost module only,and stock clutch towing. no problems.would smoke a lot at low boost.last month I added the va, my smoke level went down.not near as much smoke,way more low end and slipping clutch.I ve sence added sbc-ofe.If you what smoke get injectors,but also be prepared to buy a new clutch.
