In case you missed the news, Mountune tunes Volkswagens now too. So only a few days after it revealed its 325bhp Focus ST, it’s showing off a Mk7.5 Golf GTI with a faintly terrifying 380bhp.
While the M330 Focus kit we wrote about last week is just a few lines of code and a new air filter, the GTI Stage 2 package is a bit more… involved. While Mountune will still quite happily send you the bits to fit yourself, we wouldn’t recommend it, given the £2,099 kit includes a whole new turbocharger.
