Weistec M113K Supercharger Tuner System


Tuner System

This system is perfect for those that are looking to customize the Weistec M113K Supercharger to their preferances.  The core hardware is the same as our M113K Supercharger System with one exception.  The Tuner System does not include fuel injectors. This gives the option of choosing which injectors to run based on your power goals and tuner’s recommendation or using upgraded injectors that are already installed.  A 67.5mm supercharger pulley is included with the system to run 12-13psi on an otherwise stock car.  Smaller supercharger pulleys are available for those that want to run higher boost.  After installation, an ECU calibration from your tuner of choice is required before driving the vehicle.



Stock Power 469HP / 512TQ (Factory crank numbers, actually numbers at the wheels may vary.)
Power after Supercharger Kit 646+HP / 682+TQ 
Gains 150+ HP / 170+ TQ (Gains may vary depending on other modifications)
