WHAT IS POSSIBLE ?

Performance upgrade options

The procedure for increasing the performance of your A3 8L depends on your budget, your time and your desire for more power. All in all, there are the following adjustments that we can make to increase the performance of your A3:

Stage 1: Chip tuning

Simple, cheap, effective

Chip tuning is the first, simplest and cheapest step to increase performance. The manufacturer deliberately leaves "reserves" in the engine performance, which we extract for you. Optimal power, more performance, higher torque (and even less consumption and increased longevity are possible if you choose "Eco-Tuning").

You should consider this

If you have already done other tuning measures, please let us know. We strongly advise against "standard chip tuning packages" - as often offered on the web - because installing standard chips in already tuned vehicles can be expensive later (!).

The solution

We tune each car individually with our dynamometer. Only a few companies can offer this. Unlike other chip tuning providers, we don't just send you a control unit, but check the before and after performance of your car. This is the only way we can guarantee the increased performance and safety of your car.

Stage 2: Upgrade Kit V1

"I want more!"

In addition to chip tuning, the first engine upgrade kit replaces engine parts, sports clutch, turbocharger, intercooler, fuel pump and racing catalytic converter with high-end tuning parts.

Effort

Price/Performance

The stock parts can not offer more power and would not stand up to the extra power also in terms of safety. The effort for the upgrade is correspondingly greater than with chip tuning, but that is also the power of your Audi A3 8L!

All parts have been tested by us and our customers for years and the increase in performance is regularly proven on the dyno. Imagine giving your car to a Formula 1 mechanic. With BAR-TEK®-Tuning you really do. And that's what you get.

Stage 3: Upgrade Kit V2

"I want more!"

In addition to chip tuning, the first engine upgrade kit replaces engine parts, sports clutch, turbocharger, intercooler, fuel pump and racing catalytic converter with high-end tuning parts.

The stock parts can not provide more power and would not withstand the increase in performance, even in terms of safety. The effort for the upgrade is correspondingly greater than with chip tuning, but so is the power of your Audi A3 8L!

All parts have been tested by us and our customers for years and the extra performance is regularly proven on the test bench. Imagine you give your car to a Formula 1 tuner. At BAR-TEK®-Tuning you really do it. And that's what you get out of it.

Good reasons for BAR-TEK®

A3 8L tuning since its birth

We have been tuning the A3 8L in all variants and years since it first came off the production line in 1996. The main thing is that a 1.8 T or larger gasoline engine is installed. The simple overall concept makes it the ideal vehicle for hobbyists and self-tuners, but also allows professionals like us to really get everything out of it!

More about us

Parts developed specifically for the A3 8L

Over the years, we have already made the A3 8L fit for the racetrack in several of our own projects and installed specially developed parts for this purpose and put them to the test. These are only available at BAR-TEK® Motorsport and have also been approved by TÜV. Only in this way can we guarantee maximum performance without sacrificing safety and long driving pleasure.

Our own developments

We know the teething troubles of the A3 8L

The A3 8L often has problems with the chain drive. The chain elongates and wears out. We have identified the fault and specialize in not only fixing it, but using it to your advantage. We know all the teething problems of the A3 8L and eliminate them professionally and safely tuning.
