B47 320d - Switchable Map - 239hp & 517nm.

We recently had this 320d in for our switchable map calibration, with the customer opting for the ability to have two different power levels and the choice between having a hardcut or no hardcut.

Only modification on this one was a full exhaust.

Sport - 239hp & 517nm.
Comfort - 215hp & 400nm.

With comfort utilising stock torque levels for everyday driving, and no limiter.

And sport with the increased power/torque and hardcut.

E90 335d - 430hp & 908nm.

We completed tuning on this 335d last night, and it’s probably one of the best examples we have seen in a while.

Fitted with the following:

- AET Turbos.
- R90.
- Full Exhaust.
- 2700 RPS.
- Upgraded FMIC.

The customer specifically requested to keep the tuning on the conservative side, with the power being achieved at 2.8 bar of boost. No doubt with a little more fuel and boost, 450hp could have been achieved.

430d - 423hp & 845nm.

This is the third time we have had this car on the dyno, as the customer has went from Stage 1 all the way up to 423hp over a couple of years of ownership. Seems like he’s caught the power bug.. like us all.

Overall, a very healthy example with proof that when the fuel system is healthy, these can make nice figures on the stock HPFP.

Simple yet effective set up:

- 3” Downpipe (Stock Cat Back).
- FMIC Upgrade.
- TS3 Turbo Upgrade.
- XHP TCU Software.

Datalogs showing 850nm, almost correlating to the 845nm shown on the dyno, like always our calibrations follows the correct torque model to keep the 8HP gearbox happy on a long term basis.

Primary EGT sensor reading shy of 500 degrees on a hard pull, well within the safety limitations in place.

Power was achieved at 2.8 BAR of boost with headroom left in future for a 50D HPFP install.

Technical Post…

This is mainly to create awareness for the difference between working with a tuner with calibration experience and file flashers...

Last year we carried out tuning on an F10 535d with TS1 Hybrid turbos, the catch being the DPF was still in place.

After a few months of fault free driving, the EML illuminated, stating a fault with the DPF pressure sensor.

Initially incorrectly diagnosed elsewhere as “poor tuning” the vehicle was “retuned” and magically the DPF pressure sensor fault was gone now with an additional +50hp claimed.

The customer having some doubts with the previous advice/workmanship and how the vehicle was driving, he decided to book in again with us to have a look at what's been done.

Luckily it was just in time, as soon he could have been expecting to install a new engine…

Now, we won't get into the decalibrated mess that was installed onto the ECU, but we will cover how the issue was “fixed”.

Here is what was done:

- DPF Pressure Sensor DTC deleted.
- DPF Back pressure limitation turned off.
- EGR turned off completely, with the possibility of regens being blocked from initiating.

What was the real issue?

Damaged wiring to the DPF Pressure Sensor.

After repairing, and re-installing our calibration with all relevant protections active. The DPF backpressure was showing 4.5 BAR, which is offensively high.

After a forced regen, it was back to suitable levels, and the car is back to how it should be.

This is not a post pointing the finger, but things like this, give the tuning industry a bad name.

One of the reasons we stick only within the BMW & German tuning market is that we can offer genuine expertise and quality calibrations for these vehicles.

Dealer Opportunities.

Not one of our usual posts, but moving further into 2026 we have a few new dealer opportunities for individuals/businesses interested in our tuning calibrations.

Our approach to remote tuning is slightly different to most as each of our supplied calibrations are as we would do it within our workshop. Meaning correctly calibrated files - avoiding the usual +/- percentage approach used by the majority of the industry.

We heavily limit the number of dealers per country, and select those who we feel align with us best.

If you are interested in further details & discussion. Email us @ [email protected]

Our speciality falls within the BMW & VAG range. Offering all solutions from Stage 1-3.

PD130 + GT1856 - 247hp & 530nm.

We are always hesitant booking PD’s in, because 9/10 they are usually sent on their way from mechanical issues.

This one restored faith in the platform, and made nice figures after a few map revisions.

Fitted with the following:

- JW Automotive GT1856 Gen 3.
- SACH SRE Clutch kit.
- 4 BAR.
- FMIC.
.and the rest of the usual mods.

Customer specifically requested to keep smoke to a minimum, so there is actually a little fuelling left but would obviously contribute to more smoke.

Map 1: 180hp & 400nm.
Map 2: 224hp & 500nm.
Map 3: 247hp & 530nm.

Probably one of the best examples we have seen in a while.

MK7 GTI - Stage 1 - 301hp & 500nm.

We have recently been doing some extensive development work on the Simos 18 ECU found in GTI/S3/R/Cupra platforms. Specifically tailoring the tuning for NI 97 Ron fuel.

This GTI was in for Stage 1 with some bolt on’s that the customer fitted prior to the dyno session.

- Scorpion Cat Back.
- Free flow Intake + Elbow.

Stock downpipe and cat in place.

Tailoring the tuning specifically for the cat in place, we aimed for a smooth 1.5 bar of boost tapering down towards the top to keep the IS20 turbo happy. Logs showing shy of 8 degrees of ignition timing before the end of the pull with zero timing corrections and a steady 12.2/12.3 AFR. An overall safe and sensible calibration for the specific hardware installed.

MK7 CR150 2.0TDI - New Switchable Maps.

We recently had this MK7 in to do some R&D and finalise our new switch map calibration.

This one is was fitted with:

- CR184 Turbo.
- SACHS Uprated Clutch Kit. (No more flywheel shudder)
- Full exhaust.

…and the list goes on.

Map 1 - 150hp with soft limiter active.
Map 2 - 200hp 450nm (Zero Smoke).
Map 3 - 220hp 500nm (Smoke).

These map switch requirements were specifically requested by the customer.

The charge cooler on this example had seen better days, which is where the missing 10/15hp has gone in Map 3. Inlet temps were creeping higher than we would have liked.

Video of the map switching in the comments.

M57-Swapped Cortina.

We recently helped out a customer in AU🇦🇺 with his unique M57 swapped cortina, providing both ECU & TCU calibrations.

We actually have tuned two different set ups for this customer - the first being 216 injectors with the smaller GT2260V found on the earlier E60’s. Keeping boost sensible, we achieved a respectable 280hp on the dyno.

Then the question was, “how do we get more power?”.

We advised to change over to the E90 exhaust manifold, and opt for either a GTB frame stock turbo, or a hybrid.

The infamous “777853” N57D30 turbo was sourced locally and installed along with 219 nozzles to reduce duration times and keep the EGT’s lower. (216’s are fine with this turbo also).

Now running a healthy 1.9/2 bar of boost - 320-330hp can be expected.

It’s always great to get the opportunity to tune these unique builds, even if on the other side of the world.

We offer EDC16/EDC17/MD1 diesel calibrations regularly to both private & business customers -> [email protected]

MK2 1.6 CR - 210hp & 400nm.

One for the 1.6 fans…

- Darkside 50% Injectors.
- 1550 Hybrid Turbo.
- 4 BAR.
- Full Exhaust.

With no provided Duration table, there was a little more than usual involved in getting this set up to where it needed to be.

There is actually still some boost and fuelling left, but this is where we felt was a good balance for power and reliability.

Once the injectors are rectified on these, they aren’t a bad platform for tuning…

Caddy Update:

Some recent progress on the MCB Caddy. Over the holidays I found some time to get the lights, BC coilovers and the wheels fitted. While still running the same power as before - next on the list is an upgraded turbo, and a 3” downpipe. Really curious to see how it responds to the next stage of tuning…
