    Default Boost valve install

    Got this Stinger valve to install on my 86 Turbo coupe and want to verify the connections. Does it matter what vacuum line @ the firewall tree that you tap in to? I believe I have the correct line for the wastegate connection as there was an adjustable valve already installed but that one did not have another line connected to vacuum tree? Has any installed one of these?

    Keep the hoses short, IMO.

    I would just mount it near the turbo and connect to the turbo compressor housing outlet, instead of the vacuum tree.

    If you want to play "Dial-A-Boost" from the cabin, I'd still connect the lines to the locations at the turbo itself.
