Power gains of up to  120WHP and 120WTQ on a stock vehicle without the risks of flashing!

The JB4 is the most advanced and highly featured tuning system available for your B58 powered INEOS Grenadier. Power gains are up to 120hp to the wheels (140hp crank) on a completely stock B58 engine on pump gas, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher.

No ECU flash needed and compatible with locked 🔒 ECUs

The JB4 features a simple plug & play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in-dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.

Remember the JB4 for the INEOS Grenadier does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization, but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter. 

 

JB4PRO by Burger Motorsports is our brand-new in-house adapter designed from the ground up for ease of use and reliability. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look. The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns. More information on the differences between the app options is available here.

What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and the DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.

Perfect For Sophia!
Size: 1.8in for Puppy Dogs, Size: 1.8in for Puppy Dogs
These little balls are the perfect size for Sophia who is a 7 lb Yorkie with a teeny tiny mouth. The slots in the balls make them very easy for her little teeth to grab hold of and carry. The quality of the rubber is excellent, strong and durable. They're holding up great so far! She loves them and so does her Mama! 5 stars!

Horrible, don't buy
Size: 1.8in for Puppy Dogs
I wanted to love these. They had so much potential. It's a good size. It seems like a good shape. But ... 1) first red flag should have been the packaging. It looked like it was a dollar store item that had beenblost on the shelves for years. 2) the rubber is super flexible. I was expecting it to be sturdier. I can flatten the ball without lich force. Maybe that doesn't matter. Naybe flexible is good. But I never got a chance to test out it's durability against a pup because... 3) it smelled. I expected it to smell like rubber, like most rubber toys. Rubber smell is okay. Usually rubber smell goes away. But, this was NOT a rubber smell. It smells like peppermint or something similar. It's like someone sprayed essential oils when mixing the rubber and now the smell will not leave. I soaked it in dawn soap half the day and overnight. I rubbed. I scrubbed. The smell actually gets worst the more you scrub it!!! It's like a scented marker or scented eraser, but you do NOT want the scent in a dog toy! My dog cannot smell the food in it because the smell of the weird mint-like scent is so overpowering. He saw it had food, and wanted it, but every time he started sniffing wildly, he would recoil. Whoever thought it was a good idea to scent this was WRONG. Mint in the form of an essential oil is extremely poisonous to dogs!! So, why they would put a mint-loke scent ijto the dog's rubber treat toy is beyond me. I would return this if I hadn't throw out the package immediately. I considered pulling the package out of the trash once i realized the scent issue but other trash had already been dumped into the trash can over it and i didn't want to dig through trash. The ball is still soaking in soap. I scrubbed again this morning. I let obe dry out. No luck. It actually seems to get worst the more you scrub, like it really is embedded in the rubber itself. Yuck!!!

Great enrichment
Size: 2.8in for Small & Medium Dogs
These are great for our 3 dogs, they’re durable and strong. The pup ford training treats fit great into these and it takes our dogs a good bit to get all the treats out. Easy to clean and a great enrichment toy, will buy again!

My dog looks forward to this every day
Size: 2.8in for Small & Medium Dogs
My dog used to have separation anxiety every time I left the house. I tried to find things to distract her when I left, but nothing kept her attention long enough for me to get out of the house. I stuff treats in this ball and she keeps focused and gets all of the treats out. Perfect solution to keep her occupied as I leave for work. Very easy to put treats in and I’ve had it for about 6 months now, which is great because my dog chews toys to pieces within days! High quality ball. I love it so much (well, my dog loves it so much), I bought one to give my neighbor’s dog.

Good toy, wish it was slightly bigger
Size: 2.8in for Small & Medium Dogs, Size: 2.8in for Small & Medium Dogs
I got the medium to large size ball for my elderly boxer who has suddenly taken to chewing on everything. The toy has been a decent purchase. Pros: not incredibly stiff plastic for elderly dogs. Easy to manipulate to put treats in the spikes. Easy to clean. Seems engaging for my dog. Cons: probably not for super chewers. This size is probably too small for large or extra large dogs. My dog can easily fit this in his mouth and I wish it was just a little bigger. The ball can only hold one mini milk bone per slot, so it makes for treats to be really easily pulled out. Can't comment on durability yet, haven't had it for long enough. Overall, I like this toy. I just wish it was slightly wider or bigger.
