Remote ECU tune · 3.8TT VR38DETT
A custom Stage 1, 2 or 3 calibration for your Nissan GT-R VR38DETT, built by hand by a real tuner from your own stock file and datalog, and back with you within three hours of the file arriving. We tune these cars remotely, worldwide: you read and flash with your own HP Tuners interface, and you pay only once the tune is delivered.
Stock vs tuned
From the factory the Nissan GT-R VR38DETT makes 480 hp and 434 lb-ft (588 Nm). A Stage 1 tune typically adds 50–75 hp and 44–66 lb-ft, for around 530–555 hp in total. With bolt-ons and a Stage 2 calibration that grows to +100–185 hp, and a Stage 3 build — a hybrid or upgraded turbocharger, with the fuelling to support it — typically lands at 750–900 hp.
