Thanks guys for your help and information. Recently installed a boost gauge with boost bolt replacing bolt in upper intake, but have no readings.With bolt removed completely no change in engine when running. Recently having problem with hard starting warm weather or cold makes no difference. I posted these earlier but was advised by JiFaire to complete this check list and attach.
