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 its 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 and is sold in over 67 countries worldwide.

Is the JB4 a real tune?

Yes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock/flag your ECU.

Normally amazing
Color: Spiky Ball (Blue, Orange), Size: Medium
We have purchased these slightly spiky dog balls several times for our very strong jaw heavy chewer dogs and they’ve been amazing. They don’t break down they don’t get torn apart the squeakers don’t even pop out of them. So we ordered another package because we’ve lost a few outside to the lawnmower… oops and the package that got delivered today had only one ball that squeaks and the other does not. THIS IS A PROBLEM ! Unfortunately my female dog got to the new squeaking ball first and my male got to the non-squeaking ball and he was NOT happy. Basically once they claim a ball it’s theirs and the other dogs don’t go near the ball they claimed. So he’s following my female around and every time she squeaks the ball and I’m just waiting for him to attempt to take it from her causing damage to her. Normally… These are amazingly fun, tough, durable but also squeaking balls (that’s rare in a tough ball) that my dogs absolutely love. This time just got a bad batch I guess. When they squeak the dogs LOVE them. After several months of play the squeaker might break inside of the ball but the ball never comes apart or gets damaged. And we as the owners love that they don’t break down are not able to be ripped or torn even by our very strong jawed and big jaw muscle dogs. They are also great for in the house play because they’re small enough that they fit completely inside our dog‘s mouth but obviously not small enough to get swallowed so when we throw them in the house for fetch the dogs can jump up and catch them fully in their mouth so they don’t cause any damage to the walls when they hit the walls. They’re not super heavy but they’re incredibly durable. Definitely worth the price especially if you have heavy chewers or big jaw muscle dogs.

Best fun indestructible toy
Color: Crinkle Duck (Yellow), Size: Large
Truly indestructible no matter how much our oittie tries. She has owned it for three months works at destroying every day with no success. She carries it everywhere. Best purchase for chewer, more fun than the popular rubber heavy duty toy. Do not hesitate your pup will thank you for this fun distraction.

My dog loves this toy!
Color: Bunny (Gray), Size: Large, Color: Bunny (Gray), Size: Large
High quality, big toy, perfect for a medium to large size dog. After a few months of serious chewing I had to buy another one, but well worth the money! Rocky loves it.

Great toy but if your dog is an aggressive chewer, please think twice.
Color: Crinkle Chicken (Brown), Size: Large
I received this on May 23rd and on June 8th, after playing with this thing every day, our recently acquired 36 lb dog finally ripped it open and got out all the plastic and the squeaky part. Lily Belle will miss you, chicken. Lily loooooved this toy! She'd toss it in the air, chew on it, pull it with her teeth etc. but as much as she loved it, we won't replace it. It's just not durable enough for her. If your dog is an aggressive chewer, you might want to try a different toy. I hate that this lasted just a smidge over two weeks because Lily seemed to truly enjoy this toy. RIP, squeaky chicken!

Great Value Toy
Color: Crinkle Duck (Blue), Size: Large, Color: Crinkle Duck (Blue), Size: Large
This toy has been one of my dog’s absolute favorites. He gets excited every time he sees it and will carry it around the house, toss it in the air, and keep himself entertained for a long time. The shape and texture seem perfect for him, and it quickly became one of his go-to toys over everything else in his basket. What I really like is that it holds up reasonably well for the price. It’s definitely not indestructible, and after a lot of play, it will sometimes start to rip—usually around the feet first since that’s where my dog tends to grab and chew the most. But honestly, considering how affordable it is, I don’t mind replacing it when needed. It’s inexpensive enough that rebuying feels worth it because he genuinely loves it that much. I’d rather keep buying a toy he is obsessed with than spend more on something that just sits untouched. It’s fun, cute, and keeps him happy, which is what matters most. Overall, I’d definitely recommend it for dogs who love plush toys and playful chewing.
