Cheaper, cheaper, cheaper and still higher performance data on the website ....

If you are looking for such lurid offers ....

Are you wrong with us? !
Are you not critical enough ?
Should you examine the contradictions of the written texts more closely.

Check us - our technology is your answer !

Trust us !

We have already informed on the page Speedkit - Technik that we attach great importance to the highest quality and technical know - how in the production of the Speedkit.

However, not only the technology itself belongs to the high quality standard. Many additional factors round off the quality of our company and the Speedkit. Many customers in Germany confirm this philosophy by their satisfied recommendation.

Our competitors emphasize the quality of their products with brisk advertising slogans. These are for example:
Chiptuning control units of the latest generation
Most intelligent technology for your vehicle
Driving pleasure guaranteed: with our Powerbox
World first

... we not only have slogans but also inform you about facts that are better avoided in advertising.


Honest, serious and reliable - thats Speedkit!


We rely on many years of tuning experience

Gerald Reinert has been involved for over 21 Years with the technology of the powerboxes. This experience and technical know-how is fully implemented in the Speedkit. We are proud to offer you a sophisticated high-end chip tuning product at a low cost price.


Tuning is a matter of trust !
