When the TVSV is disconected I'm only suppose to be making 5 psi right? Im making about 11 to 12! is this normal. Motor is JDM Gen2 3s-GTE.

How is it disconnected? Is the 2nd port on the actuator plugged/capped?

If there are no leaks or restrictions in the boost contyrol system, and the T/VSV is properly disabled, you should be making ~ 7 psi.

The previous owner just ran a small vaccum line from one side of the TVSV to the other side of the TVSV(looped it)

Which of the following did he do?

1. Did he run one piece of hose from the in port on the TVSV to the out port? If so what did he do to the two hoses that previously attached to the TVSV? If he plugged them, you should be running about 7 lbs. of boost. If he left them open, you virtually have no boost controller.

2. Or, did he insert a coupling into the hose that once connected to TVSV in port and connected the hose that once connected to the out TVSV port to that same coupling? That would be by passing the TVSV, which pretty much eliminates boost control.

In orecer to properly disable the T/VSV,and to run minimum boost level, you must block flow OUT of teh actuator. If the 2nd port (T/VSV port) is not capped or plugged somewhere, you will not have any real boost control.

If you have any doubts,(and I DO) just cap/plug the 2nd port on the actuator. Then the T/VSV is definitely "disabled".
