hi guys i installed 2 tial q bov's on the cold side piping of the intercooler , I was wondering do you guys run a source before or after the throttle body? I drilled and made 6mm outlet source on each side before the tb, Each bov with an individual line from the source to the bov using 4mm silicon hoses, Now i notice the air coming out ins't as much as it should( i have the correct spring -11 which matches my vacuum), So after more reading other ppl suggest the source should be after the tb , as the source behind the tb is boost only, And the bov needs vacuum source as well and that is found after the tb, So shall i drill the another source after tb , t the hose from behind the tb to a new hose after the tb then back again to the bov's, Or shall i cancel the source behind the tb and just use the new source after tb ..
thanks guys
