Which TuningBox???

Hello,

I would like to purchase a 'tuning box' for my Golf 3 90PS TDI. I have done some research and am not sure which one to choose. The most popular ones seem to be Alpine, Authal and SpeedBuster. Which one would you choose or recommend?
Have you had any experience with any of these three, or do you have any other recommendations for a manufacturer?
Many thanks already!!!!

Best regards, Golfi

Hi

. . . when it comes to idling and hesitation.

Furthermore, it can be switched off with a cable - which is very important to me.
This ensures that will not automatically disable the box if it detects a faulty phone or something similar in the area, even when you need all your power to successfully complete a maneuver, such as avoiding a dangerous overtaking situation.
Any fatal crashes caused by radio-controlled speakers will, of course, never appear as such in the statistics, because the only cause mentioned is "wrong overtaking" - due to the lack of statements from the occupants...

Authal also comes with TÜV certificates and can be easily registered.

Even with the (factory-sealed) default settings, it's not a brutally powerful box that destroys materials. In my experience, with the original settings, it produced approximately 16 extra horsepower after the break-in period.
While less than the promised 20 horsepower, it still shifts very smoothly.

Disadvantages: "Normal" price level (around 1300 DM) at the time of purchase, and fewer adjustment options compared to the well-known 3-pot boxes.

I am also satisfied with the box, I can feel the increased performance, there is no significant Russian behavior, higher top speed, and the TÜV report is also included.
