APS claims that fuel economy is unaffected by the ECU upgrade, so a combined figure of 55mpg UK (44.8mpg US or 5.2 lt/100km) can be expected.
The APS Stage One kit for the VW Scirocco 2.0 TDi is priced in Britain at £499, including fitting and VAT, and is covered by a guarantee for the balance of the manufacturer's warranty.
