Show original supplier description
The Go Fast Bits T9525 Deceptor Pro II is an electronically adjustable blow-off valve (BOV) that offers precise control over turbocharger sound. Its patented Venting Bias Adjustment System, combined with remote electronic control, allows drivers to infinitely adjust the proportion of recirculated air versus atmospheric venting. This means you can choose when to hear the signature turbo spool sound and when to have a quieter operation, directly from the driver's seat. The controller can be configured to limit the maximum venting ratio, ensuring a blow-off sound without sacrificing drivability. A wiring loom is included, and the unit only requires a 12V power supply for operation. Constructed with a stainless steel valve and manufactured in Australia under ISO 9001 standards, the Deceptor Pro II is built for performance and durability. It boasts a boost holding ability of over 100 PSI. The unit features 25mm inlet and outlet ports and is designed for a huge range of direct bolt-on applications, with a compact design to fit in most factory valve locations.
