The legendary Burger Motorsports JB4 module is one of the simplest and most dramatic modifications you can perform on your VW/Audi. Whether this is your first modification, your only modification, or the finishing touch on your build, the Burger Motorsports JB4 is exactly what you're looking for. Simple, plug-and-play installation can yield results of up to 45hp and 45lb-ft with 91 octane and 4.80psi boost over stock on the default setting. Gains of up to 90 horsepower and 70lb-ft of torque can be achieved with bolt on modifications, higher octane and boost adjustment with the optional BMS Data Cable (ES3514851) or Smartphone Wireless Connect Kit (ES3514868).

Support is also provided for the IS38 turbo upgrade allowing for outputs past the 400hp level.
