Skoda Octavia VRS 2.0TFSI 6mt in to have a Josh Gander k03/04 direct bolt-on hybrid turbo fitted along with stage 3 custom dyno tuning session. Additional photos, information and dyno graph to be added

Seat Leon Cupra 2.0TSI DSG OPF in for stage 1 ecu and tcu tuning session. Modifications were D088 upgraded intercooler, APR induction kit and resonator-delete. Full pre tuning health checks, and being 2wd we added our twist on control and drivabilty strategy. A massive difference in performance and drivabilty.

Another immaculate Japanese imported Golf R! This one being a 2018 7.5R estate . This was in for a full health check, haldex pump filter cleaning, Stage 1 ecu and tcu custom dyno tuning session.

The pre tuning the customer described the issues he didn't like about how the car drove in stock form, especially with the dsg characteristics. We knew exactly what was doing his nut in and worked on the engine and tcu calibrations to completely resolve this for him.

Post test drive = huge smiles from the customer and an explanation on how we got rid of the stock calibration drivabilty issues.

Seat Leon Cupra 2.0TSI DSG OPF in for DSG service along with stage 1 ecu and tcu dyno tuning session. Stock intake, the only modification was a resonator delete to offer a better rear end sound track. Absolutely vile wet weather out there today 😫 so the post tuning test drive could be challenging. But luckily with our approach to drivabilty and control, the car was a breeze to drive and A
Enchanced ASR mapping taking care of all the potential drama, along with boost by gear setup in 1st 2nd and 3rd gears with a linear throttle torque demand.

An absolutely immaculate Japanese imported Golf Mk6R DSG in for our special offer package deal. Inlet cleaning, injector testing, full health checks and stage 1 ecu and tcu tuning session.

This stage 1 tuning session was carried out with a Direnza MTV intercooler and induction kit. The two limitations were trying to avoid deep compressor surge and keeping the stock hpfp happy. The upgraded intercooler with the reduced pressure drop it offers certainly works well across the top end. With an upgraded hpfp we could have pushed more with the stock exhaust system!!

🚨 THIS HAS TO BE ONE OF THE BEST SAVES FROM A MASSIVE ENGINE FAILURE!! 😳🔧

This Volkswagen Scirocco R 2.0TFSI was booked in earlier this week for our inlet cleaning, injector testing and Stage 2+ custom dyno tuning package.

We didn't even get the car up on the ramp before basically aborting the job! 😬

Straight away on start-up, we noticed a strange noise coming from the engine. Initially, we suspected the non-genuine copy high-pressure fuel pump (HPFP) fitted to the car.

However, after checking the fault codes, we quickly realised something wasn't right with the VVT system.

Rather than risk running the engine any further, we stopped the job there and then.

Today, we finally managed to find some time to investigate the issue properly.

AND LADIES AND GENTLEMEN... LOOK WHAT WE WERE GREETED WITH WHEN WE REMOVED THE COVER!! 😱🤯

The fact that the car had a cheap aftermarket copy HPFP fitted had already raised alarm bells. To us, that suggested there may have been some previous history or problems in that area.

Unfortunately, the customer had only recently purchased the car and knew nothing about its past. The pump was already fitted when he bought it.

Now here's where things get interesting... 🤔

The one component we couldn't find was the little button/nipple from the top of the HPFP!

Looking at the remains of the cam follower face, we're beginning to suspect that the replacement pump may have been fitted without that button/nipple in place in the first place!

We can't confirm that for certain, but the evidence certainly raises some serious questions.

Just imagine what could have happened if we'd ignored the noise, cleared the fault codes and continued with the tuning session! 💥

This is exactly why we take our pre-tuning health checks so seriously. Sometimes the best tuning decision is knowing WHEN NOT TO TUNE A CAR!

The customer is incredibly unlucky to have purchased a car with these problems...

BUT AT THE SAME TIME, HE HAS TO BE ONE OF THE LUCKIEST 2.0TFSI OWNERS OUT THERE! 🍀

Catching this when we did could well have saved him from a catastrophic engine failure and a considerably bigger repair bill.

Another reminder that a health check isn't just about finding a few boost leaks before chasing horsepower. Sometimes it's about saving an engine before it's too late.

🚨 CUSTOM TUNED… OR SOMEONE ELSE'S MAP? 🤔

Golf Mk5 GTI Edition 30 – Anti-Surge Turbo & Upgraded Actuator

This ED30 had previously been "custom tuned" elsewhere. The tuner told the customer the software included Boost by Gear and Advanced ASR, but when the customer asked for the Boost by Gear settings to be changed, apparently the tuner couldn't edit them. 🤔

The car was also suffering from some pretty horrible boost control issues. Boost would spike to 1.8 bar, then shoot straight to 2540 mbar, with boost control all over the place.

We had a pretty good idea what might be going on here...

Luckily, the customer had his own VCDS diagnostic tool, so we asked him to check a few specific measuring blocks.

We asked him to check measuring block 121-1.

Why? Because since 2015 we've been using additional measuring blocks within our R-Tech Stage 2+/3 software to monitor and configure the extra mapping features we've developed.

Over the years we've added more patches, measuring blocks and logging IDs to help us configure these features during our custom tuning sessions.

And guess what? 👀

The customer found a reading in block 122-1, one of the identifiers unique to our R-Tech software!

Suddenly, it made sense why the previous tuner couldn't adjust the Boost by Gear and other additional mapping features.

The customer booked the car in with us to investigate.

We read the ECU software and compared it against our previous work.

💥 100% MATCH!

It matched a Stage 2+ Edition 30 we'd tuned back in 2024!

The problem?

That original car had a completely different turbo and actuator configuration!

No wonder the boost control was all over the place and the Boost by Gear wasn't behaving correctly.

The customer had paid £400 for what he believed was a custom calibration. When he raised the issues, he was apparently told it was a hardware problem and subsequently blocked by the tuner.

£400 out of pocket, and still left with a car that wasn't right.

Now it's here with us for a proper custom dyno tuning session.

We'll be calibrating the ECU to suit the actual turbo and actuator combination, setting up the boost control correctly and configuring the Boost by Gear and Advanced ASR strategies to suit the car.

🔧 Here's something worth knowing!

There are several ways we can use VCDS to identify software we've previously developed, including additional measuring blocks and unique logging identifiers.

If you've got a Stage 2+ or Stage 3 tuned car and measuring block 121-1 contains one of our additional readings, there's a very good chance you're running software originally developed by R-Tech.

There's a big difference between loading somebody else's calibration and genuinely custom tuning a car to suit its hardware.

At R-Tech, custom tuning means exactly that. 💪
