Love seeing the MQB throttle dance!

Right let's sort it out 👍

Get it right 👌

To this day, engine timing related workshop activities take up a massive amount of our time... no pun intended.

Every engine needs timed and theres lots of them so no real surprise. What is surprising is how many that we do not long after they have already been done.

TFSI timing is one of the biggest for us, and its a task we do with ease. Before measurement, checks during and then also after is key and its this bit that so many fail on.

Yes you did your 2 revolutions, and yes the marks looks about right... ish. But is it actually right? And if you used the previous marks, were they even right? More not than you would think. Seriously.

Get us to do it though and it'll be right, every time. Completed, checked, confirmed!

Can’t believe we’re doing this again 🙈😎

Injection Perfection 💦

We love a Porsche round here. Maybes you've noticed...

There's been a very special 996 C4S grace the ramps here at DT for some major work of late. Its a personal car belonging to someone in the trade of whom we have a very good relationship with, but thats a whole different post.

Today we talk about classic Porsches, their injectors and sometimes what cant be seen. 👀

We remove injectors like these from a lot of classic, weekend or even track day cars. These things spend long periods of time tucked away from the salty roads, under covers waiting for their owners to return with the keys.

Its a great situation if your looking to keep the miles off a long term investment or to get that happy feeling on a summers day, but unfortunatly its terrible for your poor little injectors.

Back to this one….

Removing the fuel rail to gain acsess to the injectors revealed a common sight on early 911’s, the dreaded rusty fuel rail. The fuel rail's arent the most accessible of things, and there's two of them with three injectors per bank and they dissapear into the back of the engine bay out of sight.

Onto the injectors - with these now removed the pre service testing showed good results, however once stripped there was another story to tell.

The internal filter baskets had just started to fail, the filter material had detached from the plastic basket and this would only be a matter of time before it would degrade, detach and make its way through the injector.

Our reccomendation is to upgrade into stainless steel items and ditch the troublesome plastic filters.

Post service testing gave us some pretty much perfect balanced results across all six injectors.
These results are the dream situation for injectors that are spread across two banks - now off to porsche for a pair of new fuel rails 🙈💵

As mentioned earlier we have a bit more to show on this 996 C4S so stay tuned 😉

Bodge or Belta?

We are all for Engineering Ingenuity.

We get it... you're in a hole and there's no stock anywhere for what you need, or its so custom that theres a level of invention required to get out of it.

If you can think on your feet and get the job done then really - is it a fail?

Or if you at the side of the track and you need to get out again - will it last the next session?

Maybe's the truck has broke on safari so you need to fix it before the Lion's catch a sniff of you.

This one was a treat for us, as its a solution to a problem that has actually been executed quite well. The welding is good, the length is good. It didnt knock or bang and it was nigh on impossible to tell that it was even there.

So really is it the bodgiest of bodges? Or are you quite impressed at the fix?

Let us know in the comments ⬇️⬇️

Not another...?

We see a lot of Lapis Blue Golf R's. Sorry... not sorry.

There's just lots of them out there, and when you absolutely and positively have to get your R serviced then there is no substitute 😜

Our range of service packages cover every aspect of your cars health, and we are both equipped and experienced in the MQB range to offer this for both standard and tuned cars.

Ross's DT tuned Estate was in for its annual service and vehicle inspection which ensures that it is running just as well now, as it did the day it was tuned.

A basic service? No problem

Drivetrain, DSG clutches and anything in between?

We've got you covered 👍

Holiday Blue's

No one likes the holiday blue's. That slap, bang, wallop, crash back to reality never gets any easier. David knew this was coming very soon so decided to book his Mk7 Golf R in for a good chunk of work whilst he was away sipping his Margerita's.

Some say that he is a model of efficiency! Or maybe he just wanted to save on the Airport parking... 😜

We took his gorgeous Lapis R in and first of all assessed the car with a full vehicle health check which unsurprisingly it passed with no concerns.

Next it was a full round of Servicing using Genuine fluids and filter's at every step. No compromise, just the exact parts for the car.

➡️ Full Engine Service
➡️ DSG Service
➡️ Bevel Box Service
➡️ Haldex Service
➡️ Rear Diff Service

All of this in preparation of course for the main event, which was to take this impeccable condition, and fully serviced and prepared R to the next level -> Full Stage 2 tuned.

We lined up a full package of our preferred, tried and tested components which would ensure the best performance from the Gen 3 motor.

💥 Forge RACE Front Mount Intercooler - a super efficient powerhouse of charge cooling!

💥 Trackslag.com 4" High Flow Downpipe with Sport Cat - the best optimal flow downpipe option which will please even the grumpiest MOT testers.

💥 RacingLine Full intake with elbow - super sleek, OEM+ design and the performance to match!

When only the best will do, it is no surprise that our go to choice for DSG software is TVS. This software upgrade not only ensures that the car drives buttery smooth, but is also perfectly calibrated to ensure optimal clutch clamping and operation. There is simply no better option.

The final step is what brings the full package together, and took place whilst David was on his return leg home.

The DT Dyno ECU calibration is a meticulous deep dive into the Simos Controller logic - where the added airflow and cooling characteristics of the Stage 2 hardware, along with the already confirmed health of the car are brought together with a perfectly balanced torque control strategy.

This ECU doesnt make horsepower. It makes torque. So calibration of this torque model is what not only ensures maximum performance, but also most importantly what provides perfectly balanced drivability. The beauty of the Golf is that they have amazing potential, but its not worth having if you cant use it daily without hating it. Next level performance can still drive like a dream 👌

The final aspect of this job was full road testing. Every driving mode, every eventuality. A true tried and tested package - actually tried and tested in the real world too.

Going on holiday is always great, but coming back to this setup would surely stave off the Holiday Blue's.

Get in touch to see what we can do for your motor!

Sorry no post today ☹️

A trip down south on the A1 to see our good pals at Peron Automotive has turned into a late nighter.

Nothing but positivity ❤️

Well Done lad!!!

Chris Waterhouse has just been crowned the VWDRC 2026 VWPro Champion for what has been an outstanding season in his Audi 8V S3.

We've been working with Chris for a good few years now and have supported his racing from the early days when he was breaking 1.8t boundaries, right up to now when he has stepped up in to a much more modern beast.

We tuned his 8V S3 with a keen eye on extracting the most torque from the setup, whilst not pushing any boundaries. This is massively important for the all important reliable and consistent runs that he needed for every round of racing.

To top it off - his cat like reactions and dedication to his racing craft has resulted in him smashing even his wildest dreams. It also certainly helps having the unbelievable support from his amazing family by his side too. What a squad!!

A huge well done from all of us at DT pal !! Very well deserved.
