Introducing the Mach 2 Valve

Just like the Respons and Deceptor Pro II, the Mach 2 comes in a variety of bolt-on kits tailored for most popular turbo models. And when we say "bolt-on," we truly mean it! You won't need any extra adapters, parts, or modifications to your vehicle. Simply take off the factory bypass valve and pop in the Mach 2—it's that easy!

Versatile Configurations

The Mach 2 is designed as a 100% recirculating valve, which means it’s perfect for those looking for a bypass or plumb back option. If you're after a direct factory replacement that delivers performance without the extra noise, stick with the recirc model. But if you’re in the mood for some sound with your power, you can easily add on a conversion kit for 100% atmosphere venting!

Addressing Common Issues

Factory bypass valves often have a couple of drawbacks. They usually start opening at a certain pressure to protect your engine, which can be limiting. Plus, they aren’t optimized for quick throttle response. And let’s not forget, venting them to atmosphere can lead to engine stalling.

The Mach 2 Advantage

The Mach 2 takes care of all these concerns. It can hold unlimited boost—well, unlimited in the sense that no turbo could ever generate enough pressure to harm it! Thanks to TMS technology, you’ll enjoy maximum throttle response. And yes, you can vent to atmosphere with the conversion kit without worrying about stalling your engine!

Who is Go Fast Bits?

It all started with the passion of John Adrian to create something that other aftermarket parts cannot produce. Most parts he encountered are either of low quality and are made out of inferior materials.

He decided to take matters into his own hands and started designing, testing, and developing parts that would help improve the performance of his vehicle. Using his own car as a personal testbed, he created products that other enthusiasts later noticed, which has become the start of Go Fast Bits.

The company offers various performance parts such as boost controllers, blow-off valves, short shifters, pulley kits, and more. John Adrian also acts as the chief engineer of the company. Using his 35 years of experience manufacturing high-quality parts for the automotive industry that includes Original Equipment Manufacturers (OEM) parts, he was able to produce parts that meet the demands of his customers.

Lifetime Warranty
We live in a throw-away society, conditioned by cheap products and frequently released new models to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.

That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it.

If the fault occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.
