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.

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
