Part OutHello,*

I am selling my JB4 kit: $380

JB4 PNP (N54 Stage 3)
Intro Special $479.00*
How about up to 80hp to the wheels (100hp crank) on a completely stock car, up to 160hp to the wheels (200hp crank) on factory turbos, or up to 250hp to the wheels (312hp crank) on a fully modified car with hybrid turbos? The JB4 features a simple plug and play installation harness and built in deletion of hidden "tuner detection" codes. Compatible with all ECU versions. With over 15,000 in use and tens of millions of customer miles driven the JB4 has proven time and time again to be the safest and easiest way to extract the true potential from your N54 twin turbo!

BMS Downpipe Fix - N54 Twin Turbo Motor
$100
Eliminates timing pull, oxygen sensor miscalibration, check engine lights and tuning headaches associated with high flow exhaust systems. Installs in the ECU area and is compatible with all BMW tunes and chips. Available for the N54 twin turbo.


FSB Controller - For Upgrading Older Kits
$150.00
with the JB4 tuning system using the included FSB controller which allows for precise methanol solenoid mapping based on boost, throttle position, RPM, air intake temperature, advance, and other data elements available to the JB4 through its CANbus system. In addition the FSB feeds back an independent signal with pump loading and flow information allowing for safe and smooth progressive boost mapping. If the tank runs empty or flow drops for any reason the JB4 will safely back down performance to avoid knock. In addition methanol can be activated or disabled from the drivers seat and displayed in dash using your steering wheel control menu.

in total this comes out to $729 (before tax and before shipping)*

I am selling everything for less than half of what I paid when I first purchased it 6 months ago*
