Hello

People on this forum advice me to connect boost gauge on vacum (left side on inlet mainfold). Before I have boost gauge connect after intercooler ( on aluminium "thing" ,sorry bad english). If I connect it on vacum, in idle I have abput -0.6 and when I boosting boost dont want go under 0.1 bar, But if I connect gauge after IC , I have boost 0.7.

Any ideas?

thanks
