Default need help w/ TGV on a 02 WRX Motor

Has anyone unhooked the Tumble Generator Valve on their WRX? If so, did it cause the motor to miss and run rich at higher RPM's? The reason that the TGV's were unplugged was that im doing a motor swap into an RS and the stock ECU is not being used. Also, when you unplug the TGV. Are they supposed to be open or closed?
thanks in advance,
Yu-Pong Lam

if you can, take the manfold off and remove the TGV plates...

always closed = bad

Unhappy TGV unplugged

I've been told unplugged=closed....wouldn't do, would it? If the design is anything like a 32v 4.6l Cobra, you stand to lose a fair amount of bottom end by removing the plates in the TGV.....tumble is a good thing in certain cylinder heads.

Does anyone know for sure which way those valves will go if you just unplug them? do they stay open or shut?? Thanks

they stay shut. when i turned the turbo for a fmic, it touched the sensor and bound the tgv. the cel came on and the code was for the tgv sensor-stuck closed. if you unplug them, the car should go into limp mode. ours did anyway. if you take them off, you will have to fool the computer with a resistor, but this may not work since there is a full open and full closed value. your only option may be to port your existing tgv housings.

i've taken one off before and i regretted it, it is pre-sprung so you will have to wind it up then put it on. my car ran filthy rich and would bogg as soon as i hit the gas even slightly hard.
