This big piggy 🐷 came into us with a sore tummy…

The owner had been battling a terrible high-RPM misfire for weeks. The car had previously visited another tuning garage and was advised to replace multiple parts, spending £1000s in the process. Despite all the money and downtime, the issue still wasn’t fixed and the piggy remained off the road.

After carrying out our own diagnostics and analysing some datalogs, it didn’t take long to find the real culprit — a failed HPFP on Bank 2.

Luckily, we had a set of upgraded HPFPs in stock, so we got straight to work. Once fitted, we carried out another datalog and immediately confirmed the problem was completely gone.

With the RS6 finally healthy again, the owner decided it was the perfect time for some extra spice 🌶️

We then treated the piggy to our custom Stage 2+ ECU and TCU calibrations, transforming the way it drives and unlocking the performance it should have had all along.

Just 5 hours later, this lovely piggy was back on the road, healthy, happy, and absolutely ripping it. 💨🔥

Proper diagnostics. Proper repairs. Proper tuning.

BMW 335d - Stage 3

HASS - 471 Hp & 905 Nm

* Stage 3 ECU Calibration

This lovely BMW 335d came to us looking for a powerful yet reliable daily street setup.

After discussing the customer’s goals, we recommended a package consisting of:

✅ Performance Downpipe
✅ Upgraded Intercooler
✅ High-Flow Air Filter
✅ TurboSystems Hybrid Turbos

The results speak for themselves — a seriously quick daily driver producing some incredible power figures while retaining excellent drivability.

We’re still running on the factory fuel system, so there’s even more potential available with an upgraded fuel pump in the future. For now, the customer is absolutely delighted with the performance and transformation of the car.

Another happy customer enjoying a properly built diesel performance setup from Hass Power. 🔥

Mercedes A35 AMG

This brand new Mercedes-AMG A35 was in with us for some tasteful upgrades to enhance both sound & performance.

We fitted a full Milltek Sport cat-back exhaust system paired with a stunning Eventuri carbon fibre induction kit. The result is a far more aggressive exhaust note, improved turbo response & a much sharper driving experience while still retaining everyday comfort.

The Eventuri intake completely transforms the engine bay aesthetics with its premium carbon fibre finish, whilst the Milltek system gives the A35 AMG the soundtrack it truly deserves.

Audi RS3 8Y (2021+) - Stage 2

Stock - 439 Hp & 592 Nm

HASS - 537 Hp & 741 Nm

* Stage 2 ECU Calibration
* Milltek Downpipe
* Milltek Exhaust
* Airtec Intake

We had an amazing opportunity to be one of the first in the UK to tune this stunning Audi RS3 8Y equipped with the new Bosch MG1CS163 ECU using the Autotuner tuning tool.

The protocol only became available a few days ago, so we wasted no time getting the ECU shipped directly to Autotuner for the unlock process. Literally just 2 days later, the ECU was back with us, installed into the car, and ready for us to work our magic.

The results were absolutely incredible. With only basic modifications, this RS3 is now producing over 530+ HP and drives phenomenally.

To make things even more entertaining, we also configured an aggressive on-demand pops & bangs setup with huge flames 🔥 — designed so it only activates when requested and stays civilised during normal driving.

Safe to say… these bangs are so outrageous even Trump would be impressed 🔥
