Stage 2+ Power Upgrade - Golf GTI Mk7 / 7.5

Notify me when this product is available:

The mountune52 Stage 2+ Power Upgrade delivers breathtaking performance for the Mk7 and Mk7.5 Golf GTI (including GTI Performance Pack models) with either manual or DSG transmissions.

Based on over a decade of tuning vehicles to pass OEM sign-off, the mountune52 Stage 2+ offers the highest quality calibration, providing improved drivability, response and, of course, a substantial increase in both power and torque, even over our Stage 1 upgrade, all vigorously durability tested to provide peace of mind that reliability is maintained.

The Stage 2+ builds upon the existing recommended hardware in the mountune52 Stage 1 upgrade and in addition replaces the existing turbocharger with the latest-spec IS38 (as used natively on the Golf R).

With the turbocharger installed the software is (easily) administered yourself via our mTune handset, which not only offers multiple calibrations, it also boasts enhanced vehicle functionality, can be used to monitor gauges via the OBD port, and also includes a performance meter as well. If you already have an mTune handset then we will send you the calibration to load onto your existing handset.

A return-to-stock option is also included, together with a valet and anti-theft option too.

Power is increased to 385PS, whilst torque is raised to 510Nm (on 99RON fuel), enough to totally transform your Golf's DNA, turning it into the rawest recipe for hot-hatch DNA you'll find pretty much anywhere. The Golf GTI is fantastic fun in standard form, it's brought alive with our Stage 1 upgrade and then taken to a whole new level with our Stage 2+ upgrade.

As well as the turbocharger assembly itself, this upgrade also includes all the required hardware for installation, including gaskets, fasteners, oil filter and we also supply a set of Golf R spark plugs, too.

To achieve and maintain the quoted power figures under hard use or in hot climates, we recommend the following additional hardware not included in the kit:


  • Power increased to 385PS
  • Torque increased to 510Nm
  • Supplied as standard with Stage 2+ calibration, return-to-stock, anti-theft and valet options
  • Enhanced launch control (DSG)
  • Easy DIY installation

In the box:

  • New latest-level VW IS38 turbocharger assembly
  • All new required genuine VW gaskets, fasteners, oil filter and Golf R spark plugs

In addition (full kit only):

  • mTune handset, complete with four calibrations; Stage 2+, Stock, Valet, Anti-theft
    Also includes:
    - Gauge display (monitor OBD channels in gauge form)
    - Adjustable shift-light
    - Performance measurements (0-60, 1/4 mile)
    - Datalogger (10 hours max)
    - Fault-code reader
  • TCU calibration (DSG models only)
  • Zip-up case with mTune mount, OBD and USB cables
  • m52 badge

If you're upgrading from our Stage 1 and already have an mTune handset, please select that option below and you'll be emailed the revised calibration to load onto your existing handset.

NOTE: our optimised TCU calibration is required when upgrading cars with DSG transmission, and this is included when selecting the DSG option.
