Hey Racer X, I just installed the Tial bov on the driver side charge pipe, and put a block off plate on the stock bov on the compressor. All I did was relocate the hose that was on the stock bov to the Tial. Is this correct?? So I should or shouldn't keep the spring in, I left the stock spring in. I haven't had any kind of cel, but then again I just drove it around for a little bit. It has an ugly "turkey sounding" as opposed to the nice "QUEEF" i used to have. Is there anything I'm doing wrong??? I have a trifecta 23psi tune, DDM intercooler pipes, TB/IM spacers, SOLO center exhaust, SOLO downpipe catless, Dejon Intake, and Dejon Intercooler.
