Short answer: We provide a functionality guarantee for every tuning software we flash: If the installed optimization does not run smoothly during the warranty period, we will fix the problem at no additional cost. Not covered are mechanical defects in the engine or other hardware components — these depend on maintenance, wear, and driving style. This clarifies what we stand for.

At Stefanel Performance, we place great emphasis on providing our customers with high-quality services and products. An essential part of our offering is the functionality guarantee for our software. This guarantee reflects our confidence in the quality of our work and our commitment to our customers.

What does our guarantee include?

Our guarantee refers to the flawless functionality of the software we install. This means that we ensure that all adjustments and optimizations we make to the engine control meet the highest standards and function reliably. Should problems with the software arise during the warranty period, we will, of course, be there for you and promptly take care of resolving these issues.

Why a functionality guarantee?

The decision to offer a functionality guarantee is based on our many years of experience and our deep understanding of our customers' needs. We want to ensure that you are completely satisfied with our software and can enjoy the benefits of our optimizations without worry. This guarantee gives you the assurance that we stand behind our products and are always ready to support you.

What does the guarantee not cover?

It is important to emphasize that our guarantee does not assume liability for the engine and other hardware components. This means that we do not offer a guarantee for damage to mechanical parts or the engine itself. This decision is based on the fact that most mechanical problems are due to factors beyond our control, such as general wear and tear or improper maintenance.
