Remote ECU tune · 5.2L V8 (Voodoo / Predator)
A custom Stage 1, 2 or 3 calibration for your Ford Shelby GT350 / GT500, 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.
