I'm running the VMS Voltage booster
https://jannettyracing.com/products/...oltage-booster
Was very simple to install and setup. This particular one comes with a very long harness that you run along the door sill under the carpet and it has a plug and play harness that you connect your gas pedal into. Similar to the Vitesse Throttle controller.
The main unit is in the back and splices into the FPCM main 12volt power supply. The rest is simply configuring how much voltage you want to send the unit and where on the throttle pedal to activate.
