I have one of those things, but I'll be damn'd if it works or not? I turn the thing on and I can hear the solenoid ticking and if I adjust the knob on the controller the ticking will speed up and slow down but whe I drive the car with it on and try and turn it while under boost nothing happens? So I don't know what the heck it's supposed to do? Is it suppose to change the boost only a couple of psi or a significant change 5-10?
