Jaguar Tuning Industry leaders VelocityAP’s custom setup was developed and tested in a dyno setting but also extensively road tested to ensure not just big peak numbers but optimum drive-ability and seamless factory integration. JLR offers this engine in a number of factory calibrations – 340BHP, 380BHP & 400BHP. All 3 versions are fundamentally the same engine with different states of tune so the final numbers for tuning combinations are the same across all versions.

Dyno tested, developed and proven on 94 Octane Pump fuel and within a very safe AFR Range.

  1. Aaron Posey

    Had an excellent experience with VelocityAP! My order was processed promptly, and the team was very responsive to any questions I had. Will highly recommend VelocityAP in the future!

  2. Alan Lemen

    Pulls great now low down. Car has might better response at all times in all gears. Makes a good car great.
    Extremely simple to do the upgrade.
    Great company to deal with very responsive to questions even at weekends.
    Would highly recommend company and product.

    VelocityAP did an amazing job on my 2017 Jaguar XF’s performance with this ECM tune. It’s a night and day difference and worth EVERY penny!

    VERY easy process from beginning to end! the crank pulley may not have been the easiest to install but it was ultimately necessary. loving the tune and what it did to the car!!

    I got the Stage I ECU tune for my 2013 XF 3.0 AWD. I’m not convinced that it adds 75 hp, but the car definately runs better, especially above 4500 rpm. Using a handheld stopwatch, I measured 6.0 sec 0-60 before the tune, 5.5 sec after. Since that’s just 1st gear and part of 2nd, at higher speeds the performance increase is likely greater. Additionally, the MPG seems to have gone up about 2 MPG as well, with highway mileage above 30 MPG! We’ll take it on some long trips this month and get a better feel for it, but so far, so good.

    It makes your car run like it really should for a sports car. In love with the results and worth the money.
    Also great cutomer service. I will continue buying their products.

    Just be careful with pops and bangs… they are HARD.

    Going to Stage 3 with the tune and double pully has transformed my 2017 XE AWD into a sleeper that’s able to surprise anyone who wants to flex 🙂 Stage 2 provided a peak over 4K RPM that was fun but Stage 3 gives it a wide powerband and even the sound is completely different from Stage 1 or 2. The freeway power and top speed are simply unreal vs. stock. Getting the supercharger pully off required a hydraulic puller but other than that the upgrades have worked great and I have had no reliability issues with the increased power. Stage 3 will kill your mileage so if that’s important stick to Stage 1 or 2 (23 MPG now). I’m waiting on my Transmission tune to come in the mail and expect even more from the car once completed. Just do the upgrades so you don’t miss a day of fun in your Jag.
