FAQ

Common questions

What is Tunify?
Tunify generates car modification guides for your specific vehicle. Enter your make, model, year, and engine and you get a guide built for that car, not a generic walkthrough. Every guide pulls from community builds, dyno results, and manufacturer specs.
Which cars does Tunify support?
Over 10,000 cars are supported, including Toyota, Honda, BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Subaru, Nissan, Mazda, Hyundai, Porsche, and hundreds more. Coverage spans roughly 1990 to today.
How are the modification guides created?
Tunify looks up your car's factory specifications and performance potential, then generates a detailed guide covering required parts, installation steps, safety notes, and expected results. Each guide is specific to your trim and engine variant, not a one-size-fits-all walkthrough.
Is Tunify free to use?
Creating an account is free and lets you add 1 car profile. Real performance numbers, build paths, and guide generation are on paid plans starting at $8/month.
What types of modifications does Tunify cover?
Tunify covers performance mods (cold air intakes, exhaust systems, suspension, turbo kits), audio upgrades (subwoofers, amplifiers, head units), aesthetic modifications, comfort and tech upgrades (Android Auto, dashcams, backup cameras), and more.
How is Tunify different from asking ChatGPT or searching forums?
With Tunify your car is already set up, so you never have to explain it again. Guides are built for your engine, generation, and region, and come as structured steps rather than a chat reply or a forum thread full of conflicting opinions.
