This turbo stuff is all pretty new to me. I've been trying to figure out what mods to do and what to remove etc. Right now I've done the following, Streetported S4 motor,acv, air pump, split air, bac, sec. throtle plates, a/c, cold start,- all gone. Fmic and piping in the works. Now the things I need help on are.. SX 6 fpr- not sure where to put it or what vaccum line to use for it. Vaccum spider rats nest- don't know what still needs to get connected. group of diff color plugs and solenoids with vaccum lines which ones to leave connected if any? I'm hoping you guys on the website can help me with this. Thanks for the help!!
