Power gains of up to 100hp and 120tq to the wheels on a stock Infiniti Q50/Q60 3.0T

The JB4 Tuner for Infiniti Q50/Q60 3.0T plug and play tuner attaches to two easy to access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. The JB4 manipulates the ECU boost control signals allowing it to modify boost levels, but does not manipulate the ECU manifold boost reference, allowing your ECU to properly map timing and fueling for the higher boost levels. The end result is something that runs as smoothly as stock only with higher boost targets under heavy throttle. JB4 features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.

Compared to the lower cost Stage1 the JB4 system adds OBDII CANbus for increased performance mapping, a variety of useful features such as data logging, boost by gear and on the fly map changes. JB4 is simply the most capable tuning system available for the VR30 platform.

Power gains with the Red Sport model which runs more boost from the factory are in the 30-50hp range depending on fuel quality, while the Silver Sport which is heavily detuned from the factory can gain up to 60hp-100hp depending on the fuel quality. The higher the octane the higher you can safely raise the boost pressure over stock and the larger the power gain.

For those using the JB4 in conjunction with an aftermarket flash map normally you'll want to run 1-2psi over the flashed boost target depending on your fuel quality.
