Have GTI 1.8T. I don't want to vent straight to atmosphere because I don't want to run rich because of the MAF sensor. SO I plan to buy a Turbosmart Dual port and recirculate most of my air. Here is my question
They sell a kompact series valve they reccomend for audis/vdubs. Is there any problem with buying the regular size dual port? What size in terms of mm would I need to get? Like 38mm or what?
