You don't need any additional components here. Simply install and have fun! You should not use Longlife oil. Better is our fully synthetic oil.

BAR-TEK® TIP!

We recommend to fill up with 102 octane fuel. This will give you more power because your engine knocks less! Of course the turbocharger should not be too old, also the engine must be in a good condition. The V-Max is always in good condition with our tuning! With DSG vehicles we always lift the torque limit. We also recommend our PCV-KILL-Kit.

For our Chiptuning V3 we recommend the NGK RACE spark plugs. So you always have a stable ignition spark and don't have to be afraid of misfiring. We also recommend our upgrade intercooler. With it you always have the full power, even at warm temperatures.

BAR-TEK® TIP!

Here, 102 octane fuel is mandatory. Always check the diverter valve! The diaphragm is often torn, resulting in a high power loss. Our tip is: Install the GFB Upgrade Pop Off Valve! The V-Max is always in our tuning! With DSG vehicles we always lift the torque limitation. Also here we recommend our PCV-KILL Kit.

You need this extra to make it last:

Due to higher loads and more boost pressure, you need reinforced pistons and connecting rods for your engine. With our forged piston & connecting rod set you can drive the V2 tuning kit to 650 PS stable and safe! You need a reinforced sport clutch to bring the power on the road. The original clutch cannot handle the increased torque. For cars with DSG transmission, you'll also need to install a reinforced DSG clutch and adjust the DSG software. You can simply contact us for this. More engine power also generates more heat, so a higher oil temperature. So that your engine oil doesn't overheat and there is always an optimal temperature and oil quality in your engine, you absolutely need an oil cooler kit! As a perfect addition we recommend to order our digital oil temperature indicator: So you always have the oil temperature in view!

BAR-TEK® TIP!

Here you have to drive 102 octane fuel. Then it is simply important to carry out the conversion cleanly. We would be happy to do the conversion for you. Here you come to our Area-51 Workshop! The adjustment of the software to the new components must be adapted individually on the performance test bench. Also here we recommend our PCV-KILL-Kit.

Das brauchst du für die optimale Kühlung:

Wenn du die volle Leistung aus deinem 2.5L TFSI herausholen willst, darfst du auf keinen Fall die Kühlung vergessen. Schon ein wenig Mehrleistung beansprucht deinen Motor deutlich! Die thermische Belastung steigt und zieht alle Bereiche deines Fahrzeugs in Mitleidenschaft, auch das Getriebe leidet unter der neuen Power. Im besten Fall reduziert sich die hart erarbeitete Leistung wieder, im schlimmsten Fall erleidet dein Motor einen kapitalen Schaden. Damit du deinen Motor sicher und standfest tunen kannst, bekommst du bei uns alles, was du für die perfekte Kühlung brauchst. Zwar ist es ideal, alle Teile im Kühlungs-Bundle zusammen zu verbauen, allerdings musst du nicht zwingend alles auf einmal bestellen. Jedes Produkt hilft dir dabei, die Kühlung zu verbessern.
