APR Releases V 3.0 Software for EA888 Gen 1 Turbocharger System Share Comments Thread (61) APR is pleased to present the 2.0 TSI EA888 Gen 1 K04 Turbocharger System! For the budget minded individual, APR is pleased to offer software and hardware utilizing an APR proprietary customized version of the factory Borg Warner K04-64 turbocharger. Originally equipped on VAG’s high output models, such as the Golf R and S3, the APR K04 Turbocharger System offers a substantial leap in power and torque all with excellent response in a reliable and stealthy, compact design. Expect lightning fast response, smooth daily driving and power that transform the vehicle into a new class of enjoyment. The APR K04 Turbocharger System features many upgrades over the 2.0T’s factory equipped IHI turbocharger, making it an excellent upgrade. The integrated turbofold design features a cast stainless steel exhaust manifold and turbine housing, integrated into one single unit. This design aids in turbocharger spool while the stainless steel construction is capable of withstanding higher exhaust gas temperature for longer periods of time than lesser materials, such as cast iron. The CNC-machined, billet aluminum compressor wheel and higher flow exhaust turbine wheel expand the turbo’s efficiency range, allowing for higher output across a wider RPM range. True to APR’s mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. Compressor surge is avoided to increase the reliability of the system without limiting the area under the curve typically experienced during a top speed acceleration run. APR’s endless pursuit of perfection has resulted in the most comprehensive 2.0 TSI K04 turbocharger system and tuning package in the world. Using 93-octane fuel, the APR K04 Turbocharger System produces an astonishing 360 horsepower and 382 ft-lbs of torque. Unlike the factory turbocharger, power stays strong and doesn’t dramatically taper towards the vehicle’s new 7,100 RPM redline. Switching to APR’s 100 octane race fuel mode, peak power and torque climb further to 375 horsepower and 408 ft-lbs of torque. APR’s calibration experts have safely maximized the full power potential of the turbocharger unit, while keeping reliability at the forefront of their calibration strategies. Dyno Testing Horsepower and torque were measured in APR’s in-house, Soundmaster dyno cell, using a Dynapack all-wheel dynamometer. Multiple stock and modified runs were conducted and the SAEJ1349 corrected results were averaged together to represent the differences between a stock and APR K04 2.0 TSI. Crank power figures were estimated based on VAG’s factory advertised results. More details including pricing information and additional images can be found on the APR Website.
