    Estimates for a healthy stock engine. The curve shape is illustrative.

    Pick your stage

    Every price below is fixed for your exact engine. No shop-rate surprises, no "it depends" over the phone.

    1. Stage 1No mods required

      Software only. More boost, sharper throttle, and the timing your engine could always take. The quickest power you can add to a stock car.

      From $899 CAD

    2. Stage 2Downpipes or exhaust required

      Built around a freer-flowing exhaust. We fabricate our own downpipes in Quebec, so the hardware and the map are made to work together. Shop AZ downpipes

      From $1,199 CAD

    3. Stage 3Hybrid turbo or built engine

      Bigger turbos, fuel and internals. Every build is different, so Tommy quotes it with you before anything is ordered.

      By consultation

    Stage 2 starts with the exhaust.

    We fabricate our own downpipes in Quebec and map the tune around them, so the hardware and the calibration come from the same shop. Catless versions are for off-road use only.

    Two ways to get tuned

    At the shop

    1. Order your tune here, then book your visit with the link we text you. We're open Tuesday to Saturday.
    2. We log your car on our 4WD dyno, stock.
    3. We flash the tune and run it again. You leave with the before and after.

    Remote

    1. Order your tune here, then book your appointment with the link we text you. Tommy calls you to go over your mods and check that your ECU can be flashed through the OBD port. Most can.
    2. We ship you AZM Flash, our remote tuning device. If your ECU is locked or can't be flashed that way, you ship us the ECU instead: Tommy and our team tune it at our shop and send it back within 7 to 10 days.
    3. At your appointment, you sit in your car with AZM Flash plugged in, and Tommy tunes it live over the call. Your stock file is saved, so you can go back any time.

    Straight answers

    Are the gains guaranteed?

    No. The numbers on each page are our estimates for a healthy stock engine. Fuel quality, weather and the car's condition move them. That's why we put cars on the dyno before and after.

    Will a tune affect my warranty?

    It can. Dealers treat software changes differently. If your car is still under factory warranty, call us before you book and we'll tell you honestly what we see.

    Do I need to drive to Montreal?

    No. Most cars can be tuned remotely with AZM Flash, our remote tuning device, anywhere we can ship it. For cars that can't (a locked ECU, for example), you ship us the ECU: Tommy and our team tune it at our shop and send it back within 7 to 10 days. Each car's page says which applies.

    What does Stage 2 need?

    Each car's page lists the exact requirement, usually downpipes. Catless downpipes are for off-road use only. We make our own and can quote the package with the tune.

    Do you tune transmissions?

    Yes, and on Stage 2 and up we recommend it. The factory TCU keeps the stock torque limits and shift points, so part of what the ECU tune adds gets clipped. Where we have a fixed price it's on the car's page; otherwise Tommy quotes it with the ECU tune.

    My car isn't listed.

    The catalogue has the cars we have a fixed price for. We tune more than that. Message Tommy on WhatsApp or call with the year and engine, and he'll tell you if we can do it.

    How does buying work?

    Pick your car and stage, add it to your cart and check out on our store. Right after your order, we text you a link to book your appointment with Tommy. He then calls you to confirm the fitment (ECU and hardware) and walks you through the next step.

    Questions before you buy?

    Fitment, mods, warranty, a car that isn't listed: ask Tommy. He answers himself, usually the same day.

    Open Tuesday to Saturday, 8 am to 6 pm.
