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 factory VVT bring performance gains previously never thought possible.
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 strongly recommend the use of a Milltek Cat back exhaust system to ensure the greatest gains possible.
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.
Also 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 , giving the feeling of a larger cubic capacity engine.
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 standard exhaust.
Custom-Code VVT ATTACK software is available for the following 1.8T engine codes:
AUM, AUQ, BAM, ARY, BFU, BUR, BUP, AMK, BKU, BJZ, BBU and BLZ.
If you already have Custom-Code Phase 1 or 2 on your car you can easily upgrade to the VVT Attack software at the discounted price of £400 inc VAT
