GFB Respons TMS valve (part number T9033) features both the GFB patented  adjustable bias venting system, and the GFB TMS advantage.
 
The  TMS range from GFB is designed specifically for the purpose of turbo lag  reduction and improving throttle response. Tests show TMS features can  help return the engine to peak boost up to 30% faster than a factory  diverter valve when shifting gears.
 
Want sound? Admit it, you do  - otherwise you wouldn t be looking at this product! Even if you only  want to hear it a little bit, only some of the time, or hide it from  your better half, GFB's unique patented venting bias adjustment system  has you covered - it allows the amount of air vented to atmosphere or  recirc to be infinitely varied to change the sound from silent to  ear-shattering or anywhere in between, with a simple flick of the wrist!
 
"  Unique adjustment to easily change distribution of vented air between recirculating and atmosphere ports.
 
"   Great for cars with sensitive air flow meters as it can be tuned to  vent just enough air back to the inlet to prevent backfiring, whilst  achieving a blow-off sound.
 
"  Direct bolt-on fitment   NO extra  parts, adaptors, or modifications to the car required   just take the  factory valve off, and put the GFB Respons TMS in its place!
 
"  Excellent value!
 
These  unique products manufactured in Australia to ISO 9001 can deliver  performance with as much or as little noise as you like; with the GFB  Respons TMS you CAN achieve a blow-off sound without throwing a CEL,  running rich, stalling, using more fuel or causing any other problems  commonly associated with atmosphere-venting valves on cars with MAF  sensors.
