Remote ECU tune · 3.5L VQ35
A custom Stage 1, 2 or 3 calibration for your Nissan 350Z / Infiniti G35, 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.
