vacuum meter and boost meter same lah...
jz that boost meter shows positive boost after 0hg.... while vacuum meter is showing negative boost (in most cases from 0 till 30hg)
thats why some people say boost meter also can act as vacuum meter.... but not so nice la... the needle stay below 0hg only.... coz no turbo spool ma... hahaha....
yaya..... any car can install vacuum meter.... worth it or not depend on u lor... during times where ur car has no problem, can use as cosmetic.... when got problem, it can show u approximately where gone wrong ma....
The AVCR on my car cannot function well, cant control the boost, any recommend shop to do the tunning?? Or just change to HKS EVC 5 will be better? yours suggestion is appreciate,thanks..
