Kraenzle Kreations started in 2024 with a simple goal: give project car owners a place to get their EFI tuned properly and their custom parts made by someone who understands the build.

I'm Zack Kraenzle, and I specialize in tuning Holley EFI systems (Terminator X/Xmax, HP, and Dominator), as well as other EFI systems. I also do custom automotive work: designing and making new, one-of-a-kind parts for your project vehicle.

Mopar cars and engines are my specialty, but I work on other makes too. I'm focused on drag and drive projects, and pro street and drag cars in particular.

Engineer by trade but fabricator and designer on the side. Even if its not car related I am up for the task of helping design and build your next idea.

What I do

• Holley EFI tuning: remote or in person

• Custom fabrication: MIG and TIG welding, roll cage work, custom brackets in steel and aluminum, rear-end housing shortening, etc

• 3D-printed parts: custom parts in a variety of plastics and colors

• Custom-designed parts: a growing line of products in the shop, with more on the way as well as custom designs to match your next project

How working with me goes

1. Tell me about your project. Send a message or book a consultation.

2. I take a look and give you a quote. The $40 consultation fee is credited toward your final price if you move forward.

3. We do the work, whether that's a tune, a fabrication job, or a custom part.

4. You drive it or use the new part and give us feedback to we can help provider a better product/service

Got an idea? Let's build it. I'm based in Waterloo, Iowa but am happy to work with customers anywhere for remote tuning or custom parts needed.
