First thing I did, and I recommend doing if you want more Power and Long reliability with the GT2 is change oil and filter at 3000km/1860miles with Mobil 1 full Synthetic 5w30 new engine formula, and always run Top Tier 93/98 octane pump fuel ⛽ these engines love full Synthetic oil/ high octane fuel and have nock senses and after you fill up go for a 10min drive at steady speed for your engine management system to learn and save your octane level, and your timing will be full advanced and Turbo boost will hit 18bar until you fill up again. I'm running Michelin Pilot sport tyres then if you want more it's tricky before possibly voiding your warranty
