VW Golf MK8 1.5 eTSI (2023) – Stage 1 Tuning

Being a 2023 plate vehicle, the first step was confirming it can be tuned before strapping it to the dyno. Fortunately, this was supported.

The car produced healthy baseline figures in stock form, with no timing withdrawal, boost pressure exactly where it should be, stable fuel pressure, and fuel trims as close to 0%.

Final results were achieved with no additional ignition timing added. Peak boost reached 1.5 bar before tapering off, with zero timing correction, fuel pressure consistently meeting target values, and short-term fuel trims remaining spot on. Overall, a very healthy example 👌🏻

Final figures: 180.8 bhp & 337.5 Nm 💪🏻

On the road, the difference was immediately noticeable. Whether cruising or giving it some beans, the car felt significantly more refined and in tune, delivering power exactly as it should. Smooth, responsive, and with a strong linear power delivery 👊🏼

The newer generation of the VAG group boost a lot higher than the previous generations with these requesting 1.85bar from factory!

Once tuned, these see 2.1bar peak tailed off!

Logs pre and post tune perfect showing a very healthy car, making awesome figures of 199.3bhp & 451.1nm

Peak power now earlier with a big torque increase from factory for all the pulling power one of these needs 🤌🏼

Customer will be back in at some point to get the TCU remapped to top the driving experience off 👌🏻
