Everyone rags on the stock On3 manual boost controller, for good reason. After finally giving up on the stock controller I picked up a Turbosmart boost tee manual boost controller, which is an air bleeder valve. A couple things I like about it right out of the gate is the detent on the knob. It gives the end user a positive way to count clicks for adding boost versus guessing on the factory On3 valve. Also the clear markings on the tee to show what does what and what goes where. Pretty easy for installation. The question is will this work better than the stock valve? After install I take the car out for a couple of pulls and datalog to see what this thing will do out of the box.

*Sorry for the sound quality when in the car, the microphone was getting drowned out by the car, however hope you enjoy the turbo noises.
