Automotive Performance Services Tunes the 2009 Audi A5

With the idea of a diesel Audi R8 gone, Automotive Performance Services unveils a different Audi performance diesel: APS recently launched two different tuning packages for the Audi A5 3.0 TDI.

The Audi A5 3.0 TDI normally produces around 230 hp and 370 lb-ft of torque, but with the APS Stage One tuning package, those figures increase to 292 hp and 430 lb-ft of torque. With power and torque figures like that, APS says it "guarantees effortless performance."

Achieving the 55-hp boost from Audi's 3.0-liter diesel V-6 was done by remapping the ECU. The new ECU simply adjusts the fueling on the engine to allow for more power. In addition to upping the power, APS has removed the 155 mph governor, allowing the owner to unleash the car's full potential (where legal, of course). Impressively, APS says the car will still achieve 40 mpg (European) combined average.

Opting for the Stage Two tuning package nets a few more horsepower as APS adds a Milltek sports exhaust system. The exhaust is stainless steel and gives the car a more aggressive, yet refined exhaust note.

The tuning costs around £600 ($980) for the Stage One system and about £1300 ($2100) for Stage Two. The conversions arebacked by an APS guarantee covering the remainder of the original Audi warranty. Unfortunately, the A5 3.0 TDI is not available in the U.S. (therefore the tuning as well), but with the addition of Audi's 3.0-liter diesel to the Q7 lineup, we may see the engine trickle into other Audi products available in the States.
