I've got the twin 65mm BBK TB also and had the same problems as you. However the only thing that was done to mine to fix all the problems we had was adjusting some sort of backpressure in the TB and this caused the gas pedal to be a lot easier to control and idling was fine. I expressed all the same problems to my shop where i go to have work done on my car and they fixed it relatively easily with this simple ajustment. I'm not sure what the exact process or term used was called, but i will be talking to them on Moday (tommorow) and can find out.
