While we know an eighth-generation Volkswagen Golf GTI is on the way to European showrooms, Mountune has a new Stage 2+ upgrade package to give the seventh-gen model a big power boost. For £2,099, buyers can push the hot hatch to 380 bhp (283 kilowatts) and 376 pound-feet (510 Newton-metres) of torque.

The key to the power upgrade is the IS38 turbocharger, which is the same part that gives the Golf R its boost. Mountune also creates a custom calibration for the engine to make the most from the different turbo. A handset lets owners select different settings, including Stage 2+, stock, valet, and anti-theft. As an option, Mountune also offers an upgraded clutch for manual models or revised software for the dual-clutch gearbox.

For customers who live in hot climates or intend to push the car hard like on the track, the company recommends adding an induction system, turbo-back exhaust, and upgraded intercooler. These components aren't part of the Stage 2+ kit.

Mountune sells the upgrade as a bundle that buyers can install in their garage. If you don't feel comfortable changing the turbo yourself, the company's Brentwood shop in the UK can also perform the work.

For comparison, the new, eighth-gen GTI has a turbocharged 2.0-litre four-cylinder engine that makes 241 bhp (180 kW) and 273 lb-ft (370 Nm). Buyers can choose from a six-speed manual or seven-speed dual-clutch gearbox. The chassis upgrades include an improved DCC system that takes into account the steering, braking, and acceleration when adjusting the adaptive dampers. Inside, there's a 10-inch infotainment screen or optional 10.2-inch display with navigation.

30 March 2020, Brentwood. mountune52 has developed its most advanced power upgrade yet for the Mk7 & 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 GTI’s peak power has been increased to 385 PS with torque increased to 510 Nm – an increase of 75 PS and 35 Nm from the Stage 1 upgrade package, reducing the 0-60 time to 5.2 seconds. With a stock Mk7 & 7.5 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 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.” 

Making the significant upgrades in performance possible, 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 performance calibration, delivering a previously unseen level of power and torque GTI owners, as well as the possibility of fully disabling their vehicle due to an anti-theft setting.

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 mountune52, allows users to truly make the most of the new calibration but all modes can be used regardless of whether the clutch has been upgraded or not. New to the mountune52 STAGE 2+ upgrade package, a TCU DSG calibration upgrade is also available for those with a DSG transmission.

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.
