Ecotune Stage 1+ ECU Upgrade Package

The Ecotune Stage 1+ ECU Upgrade maximizes performance available without the need for DPF removal! This upgrade requires the application of a Wagner Evo 2 Competition Intercooler and produces 380HP with 540 FT-LBS of torque, vehicle dependant. Gains as high as +100HP and +100FT-LBS of torque are available throughout the power band with improved turbocharger spool and throttle response.

Ecotune Stage 1+ is available either installed at our Glasgow HQ or via our at home programmer the iFlash 3+.

To get more power, the vehicle can be outfitted with a high-flow DPF removal downpipe and Ecotune Stage 2 ECU Upgrade. For vehicles with high DPF load, expect reduced output.
