A Stage 1 remap takes the Mk7 Golf GTI from 220bhp and 350Nm to around 300bhp and 450Nm on standard hardware. The 230bhp Performance Pack and the Mk7.5 cars finish in the same place, and the 265bhp Clubsport goes to around 365bhp and 470Nm because it carries the larger IS38 turbo. On the standard cars most of the gain comes from boost and torque limiter changes rather than anything exotic, which is why the figure is repeatable across so many of them.
Measured on our Mustang AWD rolling road in Maidstone. Wheel figures, drivetrain loss added for the flywheel numbers.VW Golf MK7 GTI ECU Remapping is like bolting an extra engine on without the added weight, huge results.
Volkswagen Golf 7 GTI 2.0TSI 220BHP & 350Nm 2016
Development of our Elite Race Tune for the New Simos 18.1 ECU has led to impressive results for the 2.0TSI engine in the VAG Group cars.
Our car of choice for this particular tune is the iconic Golf GTI. As with any development the vehicle was subject to data-logging to ascertain the stock Boost Pressure, RPM, Intake Air Temperatures and Ignition Timing.
This model boosts way below its turbo’s potential, which mean there is plenty of room for adjustment and the ultimate goal, safe power.
After a few runs on the dyno, we noticed that the car makes considerably more power than the manufacturer figures this was partially but not all due to the presence of a Milltek Cat-back Resonated System we had installed previously.
The stock figures for this model are 220HP & 350Nm of Torque but this example made 255HP & 414Nm of Torque.
As usual, we read the ECU through the OBD port inside the car which took all of around 10 minutes to complete. From there, we made a base tune to see what effect little changes to the ECU made to the power output.
The base tune gave positive figures of 290HP & 450Nm of Torque. Over the following few days we developed the tune further to produce final figures of 310BHP and 500Nm Torque.
Peak HP was seen at 5800rpm with peak torque at 3200rpm. The engine ran a very safe AFR consistently through the rev range on back to back to tests and data logs.

Questions we get asked
How much power does a Stage 1 Mk7 GTI make?
Around 300bhp and 450Nm from a standard 220bhp and 350Nm. The 230bhp Performance Pack and the Mk7.5 cars reach the same figure.
Is the Clubsport different?
Yes. It starts at 265bhp and reaches around 365bhp and 470Nm on the larger IS38 turbo. The 310bhp Clubsport S finishes in the same place.
Should the DSG be tuned too?
If you have the dual clutch box, it is worth it. The standard calibration caps torque and softens the shift once the engine exceeds what it expects, and tuning it sharpens the shift as well as raising the limit.
Will VW be able to tell?
Yes. VAG systems store a TD1 flag against the vehicle once a modified ECU is detected, and it stays on record. We would rather tell you that than pretend a remap is invisible.
