vaccum question.. please help with the stock engine at idle I had 18.5 PSI of vaccum. with the new engine I have 11 PSI of vaccum. is this a problem? and what might be the cause? the new engine is 9.0 to 1 CR and has a custom cam for the turbo and stage 2 317 heads. not sure if that makes any difference or not. thanks ~Guy
