📞 Ask an Expert!APR’s TTE420 Turbocharger ECU Upgrade is designed for use with the The Turbo Engineer's TTE420 turbocharger and produces an asphalt-shredding 400 HP on 93 octane fuel, and up to 442 HP using race fuel! Expect lightning fast response coupled with smooth daily driving and a much broader power band that pulls all the way to redline!
Using multiple vehicles across the world and in house, APR’s team of Calibration and Electrical Engineers mastered the Bosch MED9 engine management system to work seamlessly with the upgraded TTE420 turbocharger unit. All critical aspects of the vehicle’s platform were taken into consideration and monitored through APR’s proprietary engine management logging tools to levels often not seen elsewhere in this industry. Through proper mapping, the ECU fully understands the hardware changes and operates correctly. As such torque delivery is smooth and flat, avoiding compressor surge, limitations in the factory fueling system, and limiting stress on the factory transmission. Cam phasing operations are optimized, aiding in turbocharger spool, while allowing the engine to breathe more efficiently at higher engine speeds. Under various operational modes, lambda, ignition advance, requested torque, boost pressure levels and more were painstakingly optimized to produce maximum power without resorting to risky calibration shortcuts.

| - APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode. | ||||||
| - Max increases are based on APR's actual measured stock values and not those reported by VAG. | RON = ROW Fuel Grades | AKI = NAR North American (RON+MON)/2 Fuel Grades. | ||||||
| - Reported wheel figures measured using APR's in-house Dynapack Dynamometer with a US Spec MK6 Golf R in FWD mode with TTE420 turbocharger, APR Cast Downpipe, APR Intake System and APR Intercooler, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. | ||||||
