By altering sensor inputs reaching your ECU, it tricks your B58 into safely producing more power than BMW initially allows. 

Built by tuning experts Burger Motorsports, JB4 has customized settings to maximize gains from your B58 engine specifically, unlike universal options.

The JB4 for BMW B58 feeds your engine information to enhance timing, boost, meth injection, and other parameters.

This means tuning your BMW B58 for eye-widening horsepower through JB4 won't void your warranty.
