Exactly
And the TVSV can only raise boost from what the WG is set at. It can't lower it. --------------------  |

It can't lower it. sorry, I havent experimented with my mbc since it doesnt currently work. Ok, so if you use the tvsv and either turn it on or off, manually, then you would stay at 5 psi. |

If your WG actuator is set for 8 PSI, you can't go below that, period. -------------------- |

If your WG actuator is set for 8 PSI, you can't go below that, period. You CAN boost below 8 psi. when the tvis is activated it wont allow the car to boost past 5 psi. This is called SAFE mode. As ive heard it called. When the engine detects knock or cold temperature of the coolant temp. |

If your WG actuator is set for 8 PSI, you can't go below that, period. to reitterate what ive been saying all along, the STOCK WASTEGATE SETTING IS ~7-8PSI You CAN boost below 8 psi. when the tvis is activated it wont allow the car to boost past 5 psi. This is called SAFE mode. As ive heard it called. When the engine detects knock or cold temperature of the coolant temp. trust me, jermey will know how the ct-26 actuator works better than you, hes a toyota tech. lol besides the fact that he has one TATTOOED onto his arm!! you have the right idea, just the wrong numbers. on a 3sgte, in "safe mode" IS 7-8psi. when the TVSV energizes, it goes up to ~10-11.8psi. -------------------- Former Team 5SFTE pro member ;)
