mountune52 has developed its most advanced power upgrade yet for the Mk 7.5 Golf GTI. The Stage 2 calibration provides a significant increase to both power and torque, whilst retaining the OEM features that have seen the GTI become one of the most popular hot hatches in history.

mountune52’s expert team of engineers has put the Stage 2 upgrade through a rigorous testing and development process over thousands of miles, ensuring that the durability of the kit matches the high standards of previous upgrades.

The Mk7.5 GTI’s peak power has been increased to 375 PS with torque increased to 500 Nm – an increase of 65 PS and 25 Nm from the Stage 1 upgrade package. With a stock Mk7.5 GTI producing 220 PS and 350 Nm, the Stage 2 unlocks 70% more power, delivering unrivalled performance whilst retaining the GTI’s renowned drivability.

“This latest upgrade for the MK7.5 Golf GTI, showcases not only our performance expertise but also the continued broadening of the mountune52 product catalogue” explains Alec Pell-Johnson, Director of mountune and mountune52. “The Golf GTI is an incredibly popular car with a huge community of enthusiasts always striving to take the performance of the car to the next level and we believe that the Stage 2 power upgrade does just that.”

To facilitate the significant upgrades in performance, an IS38 turbocharger, as standard on the Golf R, is fitted to the GTI’s four-cylinder petrol engine. In addition to the turbocharger, a bespoke calibration really brings the GTI to life. Drivers are put firmly into the driving seat, with the option to choose from five distinct power delivery options, including both high-torque and low-torque calibrations as standard.

Through the use of the mTune handset, users can decide if they want more performance, changing their calibration in a matter of minutes. An uprated clutch, also available through mountun52, allows users to truly make the most of the high-torque calibration but all modes can be used regardless of whether the clutch has been upgraded or not.

Customers can either choose to fit the package from the comfort of their own home or have it fitted by one of mountune52’s expert engineers at mountune HQ in Hutton, Essex. Those opting for fitting by a mountune52 professional are also entitled to an oil and filter service.

Additionally, the mountune52 X3 Induction System, designed for the VAG MQB platform, further enhances this hot hatch, as all mountune52 calibrations having been fully optimised to operate alongside the X3 System.
