Tuner REG System, VW O2 sensor (Tuner-VW) US$399.00 This low cost, high performance air fuel ratio data logging unit is most efficiently used in conjunction with a UTEC or Dtec, but can be used as a standalone device.

Completely universal, this device allows you to raise your over-boost fuel cut so you can boost to your hearts content. While many devices completely eliminate the boost cut, the TurboXS FCD allows you to raise the fuel cut limit but still have an over-boost setting. Standard Boost Controller (BC-SBC) US$85.00 Simple, inexpensive, and effective way to control your boost level and generate more power from your engine. Bleed type boost controller allows you to increase boost approximately 12psi over your wastegate boost setting.

The adjustable bleed mechanism lets you minimize the massive boost "spike" that can occur with poorly designed ball/spring manual boost controllers. Dual Stage Boost Controller (BC-DSBC) US$249.00 The Dual Stage Boost Controller allows you to switch between two preset boost levels with the flip of a switch from inside the car. Got a high horsepower Front Wheel Drive turbocharged car that can't get off the line?

High Performance Dual Stage Boost Controller (BC-HPDS) US$269.00 The TurboXS High Performance Dual Stage Boost controller provides the ultimate in dual stage boost control. Two preset boost levels allow you to switch from "street" to "race" boost with the flip of a switch from inside the cabin - even while under full boost. The first stage includes an adjustable ball/spring boost controller that help you to get to full boost quicker. Quad Stage Boost Controller (BC-QSBC) US$399.00 Initially designed for professional drag racers, the TurboXS Quad Stage Boost Controller provides the ultimate in boost related FWD traction control. Pro FWD drag racers Brian Ballard and Jason Hunt have been using this boost controller in the NOPI Turbo 4 Street class for the last 2 seasons. In 2004 they absolutely dominated the competition winning every race except one and managing to set two world records in the process. Jason’s CRX has run a best time of 9.53@154mph making it the world record holder for fastest FWD street car without wheelie bars. Jason’s coupe managed a 9.61@149mph setting the record for the world’s fastest street coupe. Now for the first time, we’ve made the Quad Stage Boost Controller available to the public as well as the professional drag racer. NOTE: While the BC-QSBC does come with wiring harness for all three solenoids, it does not come with any switching mechanism. It is left to the user to determine how to switch on each solenoid on, whether by using a timer, or a micro-switch off the gearbox, etc. Blow Off Valve Type H-RFL (BOV-RFL) US$189.00 With new and improved styling, the BOV-H-RFL remains true to it's roots - it's still really f'n loud! Like all our valves, the RFL relieves compressor pressure surge caused by changing gears or backing off the throttle and has been used on turbo charged engines running upto 35 psi boost. If you need to ask how loud it is, this valve is too loud for you! Blow Off Valve Type H-RFL comes standard with both a mild steel and aluminum weld-on adapters. Bolt-on kits are available for most OEM turbocharged applications. Blow Off Valve Type H: (BOV-H) US$179.00 Want a valve that people notice when it goes off but don't want "RFL-loud"? The BOV Type H is the valve for you. Providing greater venting flow than our BOV-S, the BOV-H is designed for turbo charged engines running up to 35 psi. Crafted from hard anodised aluminum and brass, the valve is practically indestructable. Cable, Tuner O2 VW (Cable-Tuner-O2-VW) US$99.00 Connects the Tuner or Tuner Pro's D15 cable to the Bosch VW O2 sensor. DTEC Air Temperature Sensor (DTEC-AIRT) US$99.00 The DTEC-AIRT sensor allows for an air temperature measurement when used in conjunction with the DTEC. Dtec Ana/Digi Pickup (DTEC-AD) US$39.00 The DTEC-AD allows the DTEC to monitor important engine parameters such as injector duty cycle, throttle position, or RPM. This kit includes one digital and one analog pick-up.

Racing Bypass Valve Type H34 (RBV-H34) US$189.00 Racing Bypass Valve Type H34 vents excess pressure back into the car’s air intake making the valve ideal for Mass Air Flow (MAF) metered cars where venting to atmosphere can create a "rich" air/fuel ratio right after the valve goes off. The Racing Bypass Valve Type H is CNC machined out of billet aluminum and brass. Valve operation, while louder than most stock valves, is quiet compared to a BOV that is vented to atmosphere like our BOV-H or BOV-H-RFL.
