New JBS/C-C R32 VVT Attack Software Released

Custom-Code has been working along with JBS on the R32 3.3 24v V6 VVT calibration for nearly 2 years.

The initial reason for looking into the VVT was to compliment the Forced induction turbo kit series produced by JBS.

The latest technology and factory information has been used along with some of the best Bosch calibrators in the business to produce a product not yet seen in the VAG industry.

The complete recalibration of the R32 factory VVT bring performance gains previously never thought possible.

After 18 months of vigorous testing Custom-Code and JBS are now ready to release this product to the public.

The precise calculations needed for the calibration of the inlet and exhaust cams , along with the custom cylinder filling and torque maps make this a totally custom application.

The smallest change in back pressure over our calibration cars , can have a huge affect on the calibration of the VVT and ignition values. So for this reason we have decided to offer the VVT Attack calibration in several options, specified for use with the standard exhaust system, as well as the already proven Milltek product. VVT Attack Calibration available for:

1. Standard Exhaust System
2. Milltek high flow cat
3. JBS De-cat option
4. Milltek Cat Back

The most noticeable aspects of the Custom-Code VVT Attack calibration is the increase in low down torque, this is uncharacteristically maintained though out the rev range. With gains of 40 ft/lb torque being seen on the JBS/C-C development car (Mk4 Golf R32).

But that's not all, the improved thermal efficiency and ability to run and maintain a optimized ignition angle can give gains of 35-40 BHP.

Now normally that's all most people would need to hear, but there's more, with the VVT Attack Calibration you can see:

1. Improved thermal efficiency means your engine runs cooler and with less EGT this can result in prolonged engine and component life and improved fuel economy.
2. A Substantially smoother running engine both at idle and when on load.
3. The engine is now much more willing to rev , feels like almost like it has much more cubic capacity.
4. No flat spots or drop in torque, smooth power delivery all the way to the rev limit.
5. The improved exhaust cam calibration now allows the engine to expel the exhaust gasses much more efficiently, this give a much deeper and sportier sound to the exhaust note.

A VVT Attack car is easily identified buy the exhilarating exhaust note. Even with the STD exhaust.


This is where it gets really exciting, the VVT Attack has been fully tested on forced induction applications and is now available for the R32 supercharger application and the entire JBS TS turbo kit series.

With all the benefits listed above, the VVT Attack also has the ability to spool any turbo up to 1000 RPM earlier than any NON VVT Attack calibrated kit. This, along with a massive 80ftlb increase in torque for the supercharger application makes this a VERY exciting product.

MkV owners with DSG can also take advantage of the VVT Attack calibration. Fully compatible DSG software is also available. Improved shifting speed and change points were needed to make the most of the new torque now available.
