I have upper lower hahn charge piping, hahn intake and catless downpipe, plan on buying there intercooler and the 20g turbo within the year, I have the bov and block off plate right now, wanted to install it but have questions about how to do the vacuum lines without problems, I have a trifecta tune and will be able to tune it the day I install it for atmospheric bov just seen alot of problems people be having not understanding how to do the vacuum lines, I would assume u connect it to the intake manifold but what to do with the old bpv line? Anyone mastered the bov on a cobalt yet? Pics would help, thank you.
