Does the port under the 99-01 TB see boost

[syclone50]

Is this boost or only vacuum

 

[TRBO VNM]

depends on the setup if I understand your question.

turbo, yes it would see boost since the turbo is before the tbody. same with centri blower. with an eaton/PD blower then no, it would be vac. only.

Ya Jason, you know what port I am talking about dont you? The one just under the idle control valve. I jsut didnt know if for some reason it would only see vacuum. I have had a long day with this thing and was just burned out. I should know if it sees vacuum at idle it is going to see boost at WOT
