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.

Great and entertaining dog toy

These are probably my dog’s favorite toys currently. He loves the squeaking and they function well as a ball for fetching as well.

Our dog loved these?!!
Color: 4 Color For XS/S 2.2", Size: Small
We have a miniature long haired Dachshund named Winston and OMG HE ABSOLUTELY LOVES THESE squeaky toys. I swear he must have played with them for 6 hours straight the first time we gave it to him. He love it so much that he even took it to bed with him that 1st night. Many months later these are still his favorite toys. I think he likes the saucer-like shape of them & how they fit & feel in his mouth. The squeakers don't last very long but that's always been the case with squeaky toys & it doesn't seem to bother Winston much either.

My dog loves these
Color: 4 Colors For M/L 3.1", Size: Large
My dog absolutely goes crazy over these squeaky toys. They bounce all directions and he can entertain himself for a bit til I'm free. However, if your are trying to talk on phone or with family you might want to hide them for a while. Noisy. Lol
