The diesel version of the European market Subaru Impreza has caught the tuning attention of Unichip, a firm that as its name implies, fiddles around with ECUs. The company claims that thanks to some subtle electronic tweaks to the 2.0-liter turbo diesel engine's fuelling and boost settings, output is raised by 18HP and torque by 33 lb-ft for a total of 168-horsepower and 291lb.ft of torque.
No performance or economy figures were released, but Unichip vaguely states that "drivers reported a 5-10% consumption improvement compared to standard".
In the UK, the Unichip U-Connect upgrade is priced at £465.30 including 17.5% VAT.
