SKU: Anti-lag Full Kit

Includes a programmed chip and wiring harness to allow on-the-fly anti-lag. Select a gear, hold down the volume button, floor the car, and once boost has built up release the volume button to instantly take off under full boost. Absolute must-have for rolling races of any transmission type and works well for automatics off the line too. Requires a BMS back end flash map and ethanol fuel is strongly suggested.

Installation directions and additional details are posted here.
