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 and reduce the change interval to 10000 km.

BAR TEK-TIP!

We recommend to fill up with 102 octane fuel. This will give you more power because your engine will knock less! Of course the turbo should not be too old, the engine must also be in good condition. The V-Max is always in good condition with our tuning!

For our Chiptuning V2 we recommend to use NGK RACE spark plugs. Thus you always have a stable ignition spark and do not have to be afraid of misfiring. In order to prevent your engine oil from overheating and to maintain an optimal temperature and oil condition in your engine, you will need an oil cooler kit!

BAR TEK-TIP!

Here 102 octane fuel is mandatory. Always check the diverter valve! The membrane is often cracked, which causes you a high loss of power. The V-Max is always kept with our tuning! Here we always recommend a Catchtank Kit for engine and transmission.

You need this extra to make it last long:

For our Chiptuning V5 you need an upgrade turbocharger. We recommend our upgrade intercooler for this performance level. This way you always have full performance, even at warm temperatures. A must for this performance level is a 4" downpipe and a minimum 3" exhaust system. Due to higher loads and more boost pressure, you need reinforced pistons and connecting rods for your engine. With our forged pistons & conrods set you can drive performance over 650 PS stable and safe! To get the power on the road, you need a reinforced sports clutch. The original clutch cannot handle the increased torque. For cars with DSG transmission you also need to use a reinforced DSG clutch and adjust the DSG software. To prevent your engine oil from overheating, our oil cooler kit is also required for this performance.
For this you can simply contact us.
