yes, you need you KVAFM, it measures how much air your engine is taking in before the turbo, and sends a signal to the ECU to tell the injectors how much fuel to use. I would imagine the engine doesn't run correctly at the state those pictures were taken. Mine had a wire that wasn't connected and refused to rev above 3000 RPM, went into limp mode to prevent damage to the engine. your BVSV should have 2 ports, one that comes from the charcoal canister to it and another that runs to a vacuum port on the intake or throttle body, can't remember ATM. and as 87hilux said, get something over those cam gears or risk having to do some real dirty work to fix it. do those 3 things and you should notice a huge difference in the way your supra runs. what kind of boost is it pushin BTW? must be a little bit more than 6psi to need the FPR, looks good on it though!

umm im not sure the battery has been dead so yea but i believe it was just a couple more than 6
