Finally an upgrade kit that adds a high fuel pressure connection to the JB4 for B58/B48 Gen2 and S58 platforms allowing direct control of fuel pressure and fuel trims. Most useful for manual transmission vehicles or those running heavy E85 mixtures on a locked ECU.
It's easy to install and includes a replacement JB4 board and a fuel pressure connector harness that attaches to your existing JB4 harness.
Note this kit is not compatible with Gen1 B58 motors.
Customers who purchased their JB4 new from BMS or an authorized reseller and their upgrade kit directly from BMS can receive a $75 core refund for their original JB4 board. To take advantage of this core refund ship your original board along with copies of the original JB4 purchase receipt and your JB4 upgrade kit order number to the address on our website. Cores must be received 45 days after upgrade kit receipt to qualify.
