The GFB Deceptor Pro II blow-off valve controller lets drivers vary BOV venting behavior from the cabin, altering how much air is recirculated versus vented to atmosphere to control sound and driveability. Featuring the patented Venting Bias Adjustment System with remote electronic control, the kit includes a wiring loom, supports high boost holding, and can be configured to limit venting ratio to reduce stalling or backfiring on sensitive setups.
