APR Plus ECU Software Flash Tuning Audi D4 A8 4.0T
The APR Plus ECU Upgrade typically raises the power output of the 4.0T to 530 horsepower and 586 lb-ft of torque on 91 octane fuel with peak gains of 75 horsepower and 88 Lb-ft of torque! Expect improved throttle response and a smoother, more powerful top end with no loss of drivability or reliability.
APR's Plus program includes a supplemental limited powertrain warranty from APR which matches the terms of your remaining Factory Powertrain Warranty. For the remainder of your OEM warranty period if you have a warranty claim which is rejected by the manufacturer due to the APR plus tune the APR warranty will then allow the car to be repaired under the APR Warranty at Achtuning or any other APR Plus dealer nationwide.
The power output of the APR Plus tune can be increased further with supporting APR Stage 1 modifications such as intake, intercooler, and TCU software upgrades. Further modifications such as downpipes or high flow cats, larger turbos and upgrades from other manufacturers would invalidate the warranty. Manual transmission clutch (flywheel, flex plate, and disc) are excluded from warranty coverage. For full terms see the APR Plus Warranty Terms and Conditions.
