Description
JB4 Tuner — Toyota Supra (A90/A91, B58) — Excellent Condition
Selling my JB4 piggyback tuner, fully compatible with the Mk5 Toyota Supra (B58 engine). Plug-and-play performance with none of the permanent changes of a flash tune — installs and removes in minutes, leaving your ECU completely stock.
Why the JB4:
Significant power gains on the B58 with multiple built-in maps (switch on the fly)
Reversible — pull it before service or resale, zero trace
Safer than a flash tune: no rewriting of factory ECU files
Bluetooth connectivity for real-time monitoring and map switching via the mobile app
