Super tidy Astra J VXR back in for a map tweak. Already on our software, just needed some adjustments.

Running a hybrid turbo, exhaust, intercooler and intake. Finished up at 344hp and 380ft-lb.

Strong result, but the hybrid turbo was a bit disappointing on this one. A healthy J VXR on the stock turbo with the same bolt-ons will do 330 to 340hp, so the hybrid hasn't added much.

"Hybrid turbo" is a really vague term. It just means something has been changed from stock and not all of them are created equal.

2019 Audi Q5 45 TFSI in with us recently for a stage 1 custom tune.

No mods on this one at all, just software.

Stock: 240hp / 265ft-lb
Tuned: 300hp / 320ft-lb

60hp and 55ft-lb gained from a remap alone.

The 2.0 TFSI in these responds extremely well to tuning and the gains make a noticeable difference to how the car drives.

Finally got round to tuning my own car. Mk7 Golf GTI, stock GPF model + Sprogley Motorsport intake kit.

Stock: 245hp / 310ft-lb
Tuned: 306hp / 360ft-lb

Kept the boost fairly low on this one. A couple of Nurburgring trips planned, so I wanted to know that I can beat down on it all day without thinking twice.

61hp and 50ft-lb gained on a conservative tune with the stock turbo.

There's more in it, another 10-20hp and 10-20ftIb quite comfortably.

Audi S3 8Y 2.0 TFSI in with us recently for a custom ECU and TCU tune.

The latest generation EA888 Gen 4 engine responds amazingly to tuning and this S3 is a perfect example. Fitted with R600 intake this car went on to make some unreal gains.

Stock: 330hp / 300ft-lb
Tuned: 421hp / 420ft-lb

91hp and 120ft-lb gained. The numbers on these really do speak for themselves.

The TCU tune is a big part of the story on the newer S3s. The ECU tune unlocks a lot of extra torque, but the stock DQ381 gearbox calibration isn't set up to handle it. Without increased clutch clamping pressures, we would have to run a lower torque map on the engine side to keep things safe.

The TCU tune solves that, increasing the clutch pressures so the gearbox can cope with the extra torque properly and letting us run the full calibration on the ECU side.

On these cars the TCU tune isn't just a nice addition, it's pretty much essential to get the most out of the engine tune.
