ECM tuning modifies your vehicle engine control module to optimize performance, throttle response, and reliability based on real data.

Are your tunes dyno tested?

Yes. Every tune is validated using dyno testing and data logs to ensure safe and measurable performance gains.

Do you offer custom tuning?

Yes. All tunes are custom-built for each vehicle and its modifications. We do not use canned tuning files.

Frequently Asked Questions

Where will the Performance Lab be located? ▼

The Performance Lab will be located in the greater Atlanta, Georgia area. The exact location will be announced once the facility lease is secured.

When will the lab open? ▼

Our target is to break ground once we reach our fundraising goal. Estimated timeline is 6-12 months from funding completion, depending on facility availability and build-out scope.

Will the dyno be available to the public? ▼

Yes. We plan to host regular open dyno days where anyone can book a session. Partner shops and supporters will receive priority booking and discounted rates.

How are donations used? ▼

100% of donations go directly toward the Performance Lab build — dyno equipment, facility build-out, diagnostic tools, safety systems, and community programs. We will provide regular transparency updates on fund allocation.

Can I donate if I'm not local to Atlanta? ▼

Absolutely. Supporters from anywhere can contribute. Remote tuning clients, partner shops nationwide, and performance enthusiasts everywhere are welcome. All supporter perks apply regardless of location (dyno sessions can be scheduled when visiting).

Is my donation tax-deductible? ▼

Down Dirty 84 LLC is a for-profit business, so donations are not tax-deductible as charitable contributions. However, your support directly funds the construction of a facility that will serve the entire performance community.

Ready to Help Build the Lab?

Every contribution — big or small — gets us one step closer to strapping down vehicles, validating tunes, and serving the community from our own facility.
