Overstock Deal Gfb Deceptor Pro 2 In-cabin Adjustable Bias Valve T9514 - Hyundai I20n Easy Returns [fOp0WASL]

The latest Smartstream 1.6 T-GDi engines fitted to Hyundai's i20 N and other models do not use a MAF sensor which means that you can vent to atmosphere for that blow-off sound, if you like, without causing any driveability issues or 'Check Engine' lights.

This Deceptor Pro 2 TMS valve features dual-outlets with a full bias adjustment system that allows you to control the venting bias to your taste immediately and directly from the driver's seat.

  • DUAL OUTLETS WITH PATENTED VENTING BIAS ADJUSTMENT - CAN BE INFINITELY ADJUSTED BETWEEN FULL RECIRC (SILENT) AND FULL ATMOSPHERE (LOUD)
  • CHANGE THE VENTING BIAS ELECTRONICALLY FROM THE DRIVER’S SEAT USING THE IN-CABIN CONTROLLER
  • TMS TECHNOLOGY FOR UP TO 30% FASTER BOOST RECOVERY ON GEARSHIFT
  • WIRING LOOM INCLUDED, ONLY REQUIRES 12V POWER SUPPLY
  • HUGE RANGE OF DIRECT BOLT-ON KITS
  • 100PSI+ BOOST HOLDING ABILITY
  • MANUFACTURED IN AUSTRALIA IN ACCORDANCE WITH ISO 9001

Go on, admit it. There are times you wish you could have that signature turbo blow off sound, but you’re not prepared to listen to it all the time. GFB’s Deceptor Pro II delivers just what you need – the ability to control how loud your BOV sound is, from the driver’s seat.

To top it off, if your car typically suffers issues such as backfiring and stalling when venting more than a certain percentage of air to atmosphere, the controller can easily be configured to limit the maximum venting ratio. This way, you can achieve a blow-off sound without having to put up with the issues.

COMPLETE RANGE OF FITMENT OPTIONS

The Deceptor Pro II direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments.
