if the hose isn't connected to the Turbo Pressure Sensor the boost cut will be removed entirely.

Serious!!! thats only a sensor for the factory gauge though yeah?? Surely i dont need that hooked up for anything else??

Well thats why i have no boost cut then.

Who wants to buy a brand new GREDDY boost cut defender hehe

The only other thing is the the guage on the dash.

doesn't need to be hooked up for anything, it won't put the car into limp mode, but it means you have no protection for huge overboosting

some think it might be used as a load sensor for the engine, but i never noticed any difference in power, and the dyno didn't either.

well i guess that solves my boost cut problem that i havent experienced yet hehe

The motor is in a AW11 mr2 so there was no need to hook up that sensor anyway, which is why it didnt recieve a vac line.

Answers my question though

Cheers guys
