AMS Performance Boost Pill - Mitsubishi Evo X 2008-2015
Manufacturer Part # AMS.04.14.0006-1
The AMS Performance Boost Pill has been created to stabilize the boost in vehicles equipped with the SST transmission. Because of the clutch engagement in the SST transmission, the operation of the boost control can be at times, inconsistent which amounts to unwanted boost spikes and erratic boost control. And some of it has to do with the ECU to solenoid issues limiting you from hitting target boost. Now all of this mess can be solved with a simple, yet affordable design.
The AMS Performance Boost Pill will safely raising boost levels, without creating boost spikes. You can enjoy OEM drivability again, and it is completely reversible if you decide that you do not want it.
But please note that your vehicle must have a tune to benefit from using this pill.
