Burger Motorsports - JB4 Tuner for Maserati Ghibli, Quattroporte, Levante, & Grecale 3.0L
The JB4 by Burger Motorsports is a plug-and-play performance tuner designed to increase horsepower, improve throttle response, and reduce turbo lag while maintaining factory drivability and safety systems.
Unlike basic chip tunes, the JB4 connects to key engine sensors and utilizes advanced CANbus integration to adjust boost, timing, fueling, and other performance parameters in real time. The result is smooth, reliable power gains without permanently modifying your factory ECU.
This kit includes the JB4PRO wireless smartphone connection, allowing you to connect your JB4 to compatible iOS and Android devices via Bluetooth.
Using the free JB4 mobile app, you can:
The updated adapter installs neatly inside the JB4 enclosure for improved weather protection and a cleaner overall installation.
The default tuning map increases boost pressure by approximately 4 PSI over stock peak boost. Additional maps can be selected using the JB4 app, BMS data cable, or compatible Bluetooth adapter.
For optimal performance gains, 91 octane fuel or higher is recommended.
The JB4 installs discreetly in the engine bay and can be removed quickly without leaving permanent modifications behind. It’s an excellent solution for drivers looking for significant performance gains while retaining flexibility.
Trusted by enthusiasts worldwide, the JB4 remains one of the most advanced plug-and-play tuning solutions available for turbocharged vehicles.

We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
