The JB4 Tuner includes CANbus, full data logging, multiple performance maps, user-adjustable fuel control, boost by gear settings, WMI support, JB4 Mobile wireless compatibility, and much more. Compatible both as stand-alone tuning systems or in conjunction with performance flash maps where logging, safety, and fine-tuning tools are desirable.
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. A separate JB4 Mobile app purchase is also required.

Questions?
Small items arrive to you in under 1 week
Larger products like full suspension kits must ship freight and can take 1-3 Weeks
Instructions are included for most parts that require any sort of knowledge to install.
Here's what to do if your parts come WITHOUT instructions:
1. Some parts are genuinely common sense on how they get installed
2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video
3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer
4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed
ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.
Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way
If the part was NOT installed, we accept returns within 14 days of delivery.
If the part WAS installed (or attempted installation), we cannot accept a return.
All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.
YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.
NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.
