Porsche tuning — per-car only
Porsche tunes are available, but not as standard in-shop tuning. Each Porsche needs a ticket with the specific car — the ECU goes to TuneZilla HQ, or we rent the Autotuner tool ($1,000 USD deposit + $100/week). Call us about your car and we'll tell you the route and the price.
BMW and MINI
We do not tune BMW or MINI. Repairs and service for those brands are still available as usual — see our Service page.
Call (519) 954-7777 for pricing on your year and model.
Tuning questions, answered straight
What is an ECU tune?
A software update for your engine's computer. It changes how the engine manages boost, fuel, and timing to sharpen response and unlock power. For most cars it's software-only — no hardware changes.
Which cars do you tune?
Volkswagen and Audi. If you drive a GTI, Golf R, A3, S3, or a TDI, call us with your year and model and we'll tell you what's available. Porsche tuning is per-car only — call us about your specific car. We do not tune BMW or MINI.
How long does a tune take?
Most OBD tunes are done in a single shop visit. The flash goes through your car's diagnostic port, right here at the shop.
How much does a tune cost?
It depends on the model and the tune. Call or text (519) 954-7777 with your year and model and we'll give you a firm number before you book. No surprises.
Will a tune void my warranty?
Most tunes void manufacturer warranty and are for off road use. We'll be straight with you about the risk for your car before you decide, and there's no pressure either way.
Can a tune be removed later?
Yes, in most cases we can flash the car back to its stock tune.
What if something goes wrong during the flash?
We flash in-shop with proper tooling and backup, and we stand behind the work. If a flash has an issue, we sort it out with TuneZilla support — you're not left on your own.
Let’s get you on the road.
