Identify your Jaguar engine before choosing a tune

The 8 listed model families above cover the records currently in our library, not every Jaguar ever produced. Select the generation and factory output matching your car; a shared model badge does not guarantee the same engine, ECU or gearbox.

Stage 1 normally retains standard performance hardware; Stage 2 requires the parts specified for that engine. Some ECUs need unlocking or workshop access at our Slough workshop.

Jaguar gearbox considerations

Jaguar automatic gearbox support depends on the exact version fitted.

Jaguar questions

Can you tune Jaguar diesels?
Supported engines can be discussed. Send your registration so we can check the ECU.

Available figures are estimates, not a dyno result for your vehicle. If your engine is missing, send the registration and configuration for assessment rather than applying another variant's numbers.

    I wanted to leave a genuine review, I got my car remapped on the 5th June 2026. Making the appointment was very easy, I didn’t have to wait too long for an appointment and had the option for someone to come to my house if needed. The remap was done within an hour or so. My light did come back on a week after the remap was done, but I was able to clear it with no issues and last weekend I took a 4 hour round trip to the beach and the light did not come back on when usually it does after about 1hr into a drive. The point of my long review is I highly recommend this company and I am very happy with the service provided.

    First time tuning my car. Didn’t know what to expect but it was amazing. They explained everything to me clearly, how it works etc and before you know it my car was ready. 10/10 polite service. Will be coming back in the future with serious motors, can tell these guys are professionals judging by tons of performance cars outside.

    Really five star service I’ve only got my car the day before I messaged on a Sunday just as an inquiry was more than Happy to take time of the day on a Sunday to fit me in last minute just want to think the whole team very professional and I absolutely love my car. I felt an instant power boost and explained everything to me and packages that I can definitely most likely in the future upgrade to will be definitely coming again.

    STX Tuning were absolutely brilliant. The service was super fast — same day turnaround — and they solved an issue with my car that a main dealer claimed would cost me thousands to fix. It turned out the expensive repair wasn’t even necessary, and STX handled it quickly and professionally. Honest, efficient, and highly recommended!
