π₯ 2018 Audi RS3 DAZA β Flex Fuel Tune Complete! π₯
This 2018 Audi RS3 DAZA came in for a full flex fuel conversion and custom dyno calibration.
β
Installed a flex fuel sensor and integrated it directly into the vehicle's system
β
Real-time ethanol content monitoring displayed in the car, including the power display
β
6 selectable maps that can be switched on-the-fly
β
Custom flex fuel calibration with extensive dyno testing and data logging
After multiple dyno runs and careful calibration across the ethanol range, we were able to achieve:
π 550 HP
πͺ 700 Nm Torque
A huge improvement over the factory output of 400 HP / 480 Nm!
+ 150hp & +220nm from stock !
Hardware Modifications:
πΉ FMIC Intercooler
πΉ Forge 5" Carbon Fibre Intake
πΉ Downpipe with 200-cell catalytic converter
πΉ Milltek Exhaust
πΉ Upgraded Charge Pipes
πΉ Upgraded Ignition Coils
πΉ Flex Fuel Kit
πΉ Step colder spark plugs
The result is an RS3 that delivers significantly more power and torque, with the added benefit of automatically adapting to varying ethanol blends while maintaining excellent drivability and reliability.
From stock to 550 HP and 700 Nm, this DAZA is now an absolute weapon. π₯
π Dyno-tested, data-logged, and calibrated to perform.

Another Subaru Impreza WRX STI Type RA in for a Link plug-and-play flex fuel setup.
Proper dyno session getting the flex fuel tune dialled in across the ethanol concentration range. We stopped at E50 due to injector duty limits.
370hp / 410Nm on pump fuel.
425hp / 480Nm on E50.
Fresh setup for this Subaru Impreza GD WRX STI with a Link ECU plug-and-play install π₯
To get the car ready for tuning on our 2WD chassis dyno, we carried out the 2WD pin swap before dialing everything in properly. The setup was upgraded with a set of Injector dynamics 1050cc injectors an FMIC and an exhaust , giving the extra fuel and airflow it needed to come alive.
After tuning, the car laid down:
β’ 330HP
β’ 420Nm torque
MaxxECU Race G1 PNP kit installed on an Audi TT Quattro 180hp π₯
Setup:
β’ Stock K04-23 turbo
β’ 38mm external wastegate
β’ Upgraded intercooler & piping
β’ 630cc injectors
Results:β‘οΈ 280hpβ‘οΈ 390Nm
Thatβs a gain of +100hp and +155Nm over stock πͺ

Another successful project in the books π§
This 2005 BMW E60 came in for a full drive-in, drive-out conversion to a ZF 8HP gearbox β and what a transformation it turned out to be.
We installed an 8HP70 gearbox sourced from a 2017 BMW F10 530D, paired with a 10-pin 8HP shifter from a BMW F30. A custom-made adapter was fabricated to perfectly suit the M57 block, while also accommodating the original starter location on the bellhousing.
To bring everything together seamlessly, we integrated a CanTCU controller to manage communication across systems, along with the necessary coding on the stock CAS2 module to ensure everything runs harmoniously on the same bus.
Replacing the original 6HP26 with the 8HP70 has completely changed the carβs characteristics β smoother shifts, improved responsiveness, and a much more refined driving experience.
Drive in. Drive out. Transformed.

We had this stunning 2022 Porsche 911 GTS (992.1) in the shop for performance upgrades and a custom calibration π₯
After installing the hardware, we carried out a full dyno session with before and after runs to properly measure the gains.
This wasnβt a quick flash and send-out job β we took the time to log key parameters, monitor the data, and refine the calibration to extract everything safely possible on pump gas, while keeping factory-level drivability and reliability.
π Final Results:
Stock: 480HP / 600Nm
Tuned: 570HP / 690Nm
Thatβs a serious jump in both power and torque β transforming the way this 992.1 GTS delivers performance.
Stronger mid-range, harder pull up top, and a completely different driving experience.
Nissan Skyline R33 RB25 - 558WHP π
Another one from ProspeedParts in for a tuning session.
Done 610hp with 675nm on 1.9bar boost on pump gas 95oct.
We turn it down a notch to 1.6 bar to get 500WHP for reliability.
Ending with 544hp / 592Nm !
Should be more than enough to do the trick π€ͺ
