Welcome to Regelin-Performance



We are your competent and reliable partner in car-tuning since early 2001. We developed lots of products to improve power and reliability of your car.

Our main focus are power- and fuel save- upgrades by modifying the software in engine-ECUs of modern cars - upgrades which are usually called "chiptuning".
Power and reliability at the same time is what we are looking for - you can be sure that you will get it.

On these pages we would like to offer a selected and constantly growing assortment of tuning parts and accessories.
All products are either from own production or of proven, reliable suppliers. Some products are manufactured directly on our behalf.

We offer high quality products and services at reasonable prices.
About 95% of the products that we offer are available from stock.
A quick and easy processing of all orders and inquiries is our top priority and a matter of course.

Please contact us per mail or per phone for any questions.
