All gains validated on real cars. Factory safety parameters preserved. · Requires a one-time Autotuner bench unlock before the first flash. We do not perform the unlock ourselves — Autotuner benches are common at performance shops worldwide, and any shop with one can do it.
How flashing works
After the one-time Autotuner bench unlock (we do not perform the unlock ourselves — Autotuner benches are common at performance shops worldwide, and any shop with one can do it), every tune is flashed over the OBD port from your phone: plug in the D-Sync D1 Wi-Fi dongle, open the D-Sync app, pick Stage 1 or Stage 2, and flash. Your factory calibration is saved automatically — revert to stock with one tap, anytime.
Pricing & ordering
$900 USD — includes the license and the D-Sync D1 Wi-Fi dongle, covering one VIN. Free shipping & customs clearance to all supported regions.
