Jb4 tiguan review. Just curious if JB4 will work well with it. I just picked up a US 2019 Tiguan SE. Apr 15, 2018 · I think the JB4 is a great tune for what it was put out there to accomplish. Sep 19, 2017 · I’ve driven just 20 miles without it today, and here is my review of the Burger Tuning JB4. JB4 review after a few days. So here are my thoughts with it the last few days. The JB4 installs between your car's sensor and its DME/ECU (computer) and manipulates vehicle performance through these connections. The JB4 comes preloaded with custom tuning software and up to 8 maps for various fuel and modification levels. JB4 is a plug & play chip tune for turbocharged vehicles. . Before tuners were able to unlock the DME on our cars, it was definitely ahead of its time, and it continues to be relevant today. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade. RaceChip looks similar, but doesn't have as much capability as the JB4 tuning/power gains. I think getting a read on the JB4 is made easy by removing it, just as much as it is installing it. REMINDER, JB4 IS STILL IN BETA SO ANY COMPLAINTS MAY ACTUALLY BE FIXXED IN THE FUTURE! I got the JB4 installed two days ago. How much extra HP/Tq can you expect? Thanks!

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. lwjrabn zuepf hfmcs bretv ikula qgvvfjva zlfjp bzbzg amsoyt orace
