Selling my JB4 along with the fuel pressure upgrade kit (integrated). Both are in excellent condition and fully functional.
JB4 Tuner (with all original wiring and connectors)
Fuel Pressure Upgrade Kit installed
No Issues!
Price: $550 OBO
Regarding the fuel pressure upgrade kit: 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 those running E85 mixtures on a locked ECU.
Local pickup preferred (Jax FL), but shipping is possible at buyer’s expense.
