Stage 2+ 'Lite' Power Upgrade - ECU Software - Fully Fitted at mountune52 HQ

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 by us, the software is administered via a laptop and removes the need and cost of the mTune handset for customers that do not require that functionality.

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:

• An aftermarket induction system, like the mountune52 X3, complete with muffler delete
• Turbo-back exhaust
• Uprated intercooler


  • 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

  • Stage 2+ calibration (flashed at HQ - no handset)
