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. 

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.

Exactly as FP describes
Size: 27, Color: Deep End
Quality denim with the classic FP barrel or horseshoe leg. These are deep, dark blue rigid denim with a button fly. Hits at the ankle for me, but if you are shorter than 5'9" you may a get full length fit from these. I own these jeans in multiple colors and these are another FP win for me.

Perfect lightweight denim for summer in Florida!
Size: Large, Color: Union Blue, Size: Large, Color: Union Blue
LOVE EM. Insanely comfortable and lightweight quality denim with a kiss of stretch (perfect for summer). I pair them with tees, cropped tops, tanks or button up shirts. They’re adorable with sandals, sneaks, flats or flops. I went through about 5 pairs of jeans from different stores looking for the perfect combo of lightweight, comfy and stylish; these fit the bill. The distressed accents (a few rips and paint flecks) add interest without being over the top. The attached belt is such an adorable accent. Love love love these and will likely buy a second pair. True to size.

Super comfy, roomy, great quality!
Size: Medium, Color: Calypso Blue
These are so cute! They fit nicely, actually run a bit big but that’s probably intentional. I’m short, just a little over 5 feet tall and they are the perfect length for me. I got a medium, i normally wear some mediums and some larges. They are lightweight denim and great quality!

Sturdy fabric, well made.
Size: X-Large, Color: Royal Blue
I LOVE these pants!!! Who buys pants online??? I NEVER do, but I took the chance band I absolutely adore them!! I’m 5”10’ 200lbs and they are so super comfy and look fabulous on me too. (If I do say so myself) Wore them to the baseball game and got three compliments. Might order another pair? Seriously, they are well constructed. Good solid material with just enough stretch. The pockets are actual Pockets. I seriously love them.

Great fit, good quality, horrible smell
Size: X-Large, Color: Calypso Blue, Size: X-Large, Color: Calypso Blue
Surprisingly decent for the low price. Love the details. Fit is good, but I sized up based on the measurements (I wear a 14 but bout the XL/16-18) and I like the looser fit if them. Would honestly rate 5 stars, but there was a HORRIFIC little fragrance pie thing stuck in the bag... I'm sure, based on how many people I walk past in the world stink of hyper-scented laundry detergent, that this is not a problem for some folks, but many people also have fragrance sensitivities, and this can be not just problematic for some, but dangerous. I had to wash these jeans 4 times before the odor went away enough for me to wear them. So that was disappointing, but otherwise, I'm a fan.
