Gains are up to 80whp/100tq on pump gas and up to 120whp/140wtq on higher octane or E85 mixtures without the risks of flashing!

The ultimate tuner for your S55 powered vehicle, the JB4 tuner allows you to go from factory stock to full race, and everywhere in between, with the push of a button on your steering wheel or phone. The JB4 installs and removes easily and includes many unique features not found in any other tune including user adjustable 1st and 2nd gear boost limiting, map switching in dash, electronic wastegate control, ethanol fuel support, and built in advanced CANbus based diagnostic tools. Installation is completely removable with no splicing or cutting of factory wires.

The JB4 is compatible with the factory flash map, competition package flash map, all off the shelf flash maps, custom tuned flash maps, or any flash map you choose to load! For those who don't mind flashing BMS provides free back end flash maps designed to optimize performance for specific builds and fuels saving you hundreds of dollars and many hours of time on custom flash tuning.

For the latest performance results, updates, firmware, and map guide be sure to visit N54tech.com.

For those running aftermarket turbocharged systems with aftermarket Tial wastegate(s) we have a special version of the S55 JB4 specifically to control them. Email us so we can manually invoice you for the JB4_S55_TIAL version.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.

Damages and issues
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.


Exceptions / non-returnable items
Certain types of items cannot be returned, Burger Motorsports does not allow returns, custom products (such as special orders or personalized items), and air filters can not be returned. We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item.

Unfortunately, we cannot accept returns on sale items or gift cards.


Exchanges
The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.


Refunds
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. Certain circumstances will require a restocking fee of up to 25% at the discretion of Palenon Performance. (Examples of these circumstances include but are not limited to multiple failed delivery attempts, modified or damaged products and packaging, etc.) If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.

Handling

If the item is shipping from us direct, you will receive a tracking number within 1 business day. Most orders fulfilled at our warehouse will ship the same business day if ordered by 12pm MST. If the item is being drop shipped from the manufacturer, we cannot guarantee a tracking number within 1 business day. If an item is being drop shipped, we cannot guarantee the 24 hour (1 business day) processing time. A purchase of expedited shipping at checkout means that once item is ready to ship, it will ship using the upgraded shipping method. Some manufacturers require 3-5 days to process orders. Purchasing expedited shipping may speed up the processing time of your order, but we cannot make any guarantees in relation to faster processing time on the manufacturer’s end.

Cancellations

If you used a credit/debit card or PayPal to place an order and decide to cancel or return your order for any reason, a 5% merchant fee will be passed along to you (8% for Shop Pay installments). Some manufacturers can take up to 7 business days to ship out orders. If an item is out of stock we will reach out to you within 48 hours to confirm you would like to proceed with a preorder. If the item is listed as custom-built/ built to order within the description, or if the ETA or average lead time is visible on the product page at the time of ordering and you are cancelling inside of that ETA/lead time you will be charged the merchant fee. If the cancellation is outside of the time frame the merchant fee will not be charged to you for canceling.
