Save your money. Those things are usually just a resistor that changes a sensor reading or the reading going to the ecu. I think they typically richen the air/ fuel mixture so at certain throttle openings it may run better, but at others it may run worse. Just my take on them.

Give me the $40 instead, you'll feel the performance gain with a lighter wallet.
