O.CT Tuning Spiffs Up the Audi A4. 2.0 TDI and A3 1.8TFSI Convertible

Yet another tuner is taking a swing at the new Audi A4 and A3 Convertible models. This time its O.CT Tuning that has released new performance kits for the A4 2.0 TDI with 120HP and 143HP as well as for the A3 Convertible 1.8 TFSI. For the diesel powered A4s, a reprogrammed ECU boosts output of both variants of the 2.0 TDI to 168HP and 375Nm or 277 lb-ft of peak torque. According to O.CT, the 168HP A42.0 TDI accelerates from 0 to 100km/h (62mph) in 8,0 seconds versus the 143HP stock model's 9,4 sec.

Furthermore, the Austrian tuning house claims that while the standard A4 2.0 TDI needs a distance of 1,600 meters (about a mile) to reach a speed of 180 km/h or 112mph, O.CTs version hits the mark after 1,100 meters or 0,7 miles.

Similary for the A3 Convertible, , O.CT Tuning's upgraded ECU adds an extra 45HP to the 1.8 TFSI 160HP engine for a total output of 205HP that helps the car accelerate from standstill to 100km/h in 7,3 seconds, or around 1 second faster than the standard model.

Even though O.CT Tuning concentrated on the A4 and A3 Convertible models, apparently the software upgrades apply on any models with the same engines.
