BAR-TEK® tips!
We recommend filling up with 102 octane fuel. This will give your engine more power because it knocks less! The engine should be in good condition and the turbocharger should not be too old.

To bring the extra power on the road, you need a sport clutch, because the original can not transfer the power. For the conversion to K04-001 turbocharger you have to install a 3" downpipe and our upgrade air mass meter.
We recommend that you buy the Level 3 Kit right away. With the level 2 kit, without modified injectors and upgrade manifold, the performance gain compared to chip tuning is not quite as high. This is because the 180 PS 1.8T engine already has a slightly larger turbocharger.

Also here you need a sports clutch, because the original one can't transfer the power. For the conversion to K04-001 turbocharger you have to install a 3" downpipe and our upgrade air mass meter.
With the tuning kit stage 3 you have the extended extension stage of the kit 2. Here you have 380 ccm injectors and an upgrade manifold as well as an again optimized software! If you have already installed a downpipe, an intake hose and an upgrade intercooler, you can continue to use them. With an upgrade intercooler you also have the complete power available in summer!

320 PS: That's an announcement! To drive this power, you have to replace your connecting rods with h-beam connecting rods. A sports clutch kit is required to make the 320 PS perfect. For the exhaust you should use a 76 mm exhaust system. For the correct oil temperature, an oil cooler must be installed!
A good chip tuning is required for this conversion. You can send us your control unit or have your vehicle tuned directly in our dyno. Another tip from us: If you have installed the small 280 mm brake system, this is no longer up to the high performance. You can convert it to a Brembo 4-piston brake or a 320 mm brake (e.g. from the Audi S3).
