Is a vac line mixed up somewhere

[quote=123hotchef|p379524]Is a vac line mixed up somewhere[/quote]Checked pipes with mates car all seam to be hooked up right when it first happ it was running but with reduced power that is why I changed turbo but it now looks like this may have been original fault before I did all this work

you got any black smoke in the exhaust? ... if so , is the EGR valve still on it, as it may be sticking. When my EGR valve was sticking it was lacking power and belching black smoke, eventually wouldn't run.....
