No not for me, for my car. I was reading the new Ecklers's C4 catalog and ran across a couple of items that I can't remember ever seeing mentioned on the Guru and wonder if anyone has had any expieriance with any of them.

One is the Throttle Performance Switch which is said to instantly improve throttle response and delivers max rate of fuel and timing advance. It plugs in line with the throttle position sensor.

The other one is the Air Intake Temp sensor relocating kit. This is supposed to dramatically improve performance by hanging the air temp sensor out in the cool air.

Also the ever present throttle body air foil that will add 11.8 hp and 12.5 ft'lbs of torque. TPiS has said that they came up with the air foil and have sold so many, no one even questions it's power adding abilities. Yet I know the Guru has said they don't work.

Just interested in what you guys think. I am always looking for performance adders.
