Who supplies the parts? That’s down to you. Supply the parts you want fitted, fit them yourselves or we can fit them for you. We’ve never been a firm that says we won’t tune something you’ve put together yourself but just remember if you fit something and it doesn’t work, its on you not us, if it takes us 4 hours to diagnose why it doesn’t work because you fitted it wrong, we aren’t doing it for free!

In all cases we will offer full customer service and aftersales support. As anyone will know we offer COMPREHENSIVE after sale service where no matter the issue we will help, 90% of cases its unrelated to what we’ve done and to find the problem we will do as much as we can for free, your satisfaction is our objective.

 

Differences between the S3. Golf R Engines and the AXX/BWA

The number one difference is the compression ratio. The 8p S3 Golf Mk6 R Golf Mk5 Edition 30 Cupra K1 engines with the K04 turbo all run lower compression ratios of 9.8:1 whereas the AXX engine runs at 10.5:1 and the BWA 10.3:1. Whilst this will have an impact on the tuning and could potentially be beneficial it means that this isn’t simply a matter of sticking the turbos from an S3 and forget the rest.

For example with more compression you will have more low end torque and the turbo should get up to speed faster, potentially suffering less turbo lag. The biggest issue to higher compression and the reason VAG reduced the compression is related to boost. Because the turbo makes more boost with the higher compression ratio it is more likely to ping/pink/knock. Thus all Stage 3 tuning at Llandow Tuning includes full plex knock detection during a live tuning session.

Knock Detection and Live Tuning

 

To ensure the map is safe and to safeguard the engine and of course us from being accused of blowing an engine up with poor tuning, we will use the latest Plex Knock detection during a live tuning session. The tuning session alone is normally billed at £900 but it is included in this package at a reduced rate.

Warranty

Naturally all tuning carries risk. As does driving a worn stock engine. We will provide complete after sales support

 

 

Cost

Our Stage 3 tuning including live dyno tuning and necessary ECU modifications for KA04 modified AXX and BWA engines is £520

Fitting for the parts above is available and typically will take a day with everything. We’re happy to negotiate this or you can fit the parts yourself.
