    2019+ cars have the Gen 3 Coyote motor that breathes a little better than the previous cars but is also hampered by the addition of a GPF into the exhaust system. In the context of remaining street legal (i.e. retaining cats and GPF hardware), and excluding a supecharger is a tune and filter the only real viable bolt-on solution for more power on these cars? Has anyone developed a high flow cat/GPF solution yet? Does a resonated H or X pipe from Borla or Magnaflow actually flow better than the stock mid pipe resonator box?

    Not that I'm particularly complaining about the power available, but I wondered if in the UK there were tuners out there capable of tuning a 2019+ car with a GPF, if the gains are worth it, and if there are any other modifications that are on the market that are worthwhile that don't delete the cats/GPF.

    Thanks.

    Also interested in this thread.

    About to pick up my 2019 GT and want to make some mild upgrades and stay within warranty if available. I look forward to the experts in this forum chipping in with their pearls of wisdom.

    i think most yank tuners are refusing to tune for gpf's now and I wouldn't trust any UK based tuner

    I started a thread asking a similar question about achieving 500bhp, bolt ons & "Toon".

    I believe Palm Beach Dyno may toon U.K. GPF equiped cars.

    How can I tell what Gen my engine is? Reason being I originally purchased a 2019 stang but then needed an engine replacement which they then put in a oct 2017 built engine.

    Asking because I'm interested but now I have no idea where I stand

    Confirm with the people who replaced your engine.

    However, seeing as you've an MY18> car, I'd expect your car was built with a Gen 3 Coyote and so it should have been replaced with a Gen 3 engine.
    Generally, converting a car with a Gen 3, to take a Gen 2 I would expect to be an even larger job than fitting a same generation replacement engine.

    Makes sense, just wondered if there was an easy visual way to tell the difference between the generations

    Im no expert, but considering the big engine cover isnt interchangable then that alone would be the giveaway?

    I think this thread went in a different direction than I expected.

    I have decided to add a bigger throttle body and cold air intake, alongside a Borla cat-back. Once the parts arrive and are fitted I think it will benefit from a mild tune.

    So I am curious to know if anyone knows of tuners that will provide tunes for GPF cars.
    I saw the reply about Palm Beach possibly being able to help.

    Are there any other people that have had success on a GPF car with other tuners?

    Thanks

    I dyno everytime I do somenthing
    2018 pp1 10speed
    Borla atak +12-14whp
    Tune 91oct (about 95 for europe) +9whp
    Tune 96(like 100 europe) +20whp
    JLT +22whp on my tune 96oct (inuse the car for the track to if you do street you might heatsoaking a little)

    Next for me e85 (impossible in europe)
    Headers add 10-12whp extra however impossible for me with my borla atak (too loud)
    Then you need to start to digbinto engine components. Like camshaft etc.

    Hope this help

    So, for the sake of argument if we assume your car started at 400whp bone stock, you have gained:

    13 + 20 + 22 = 55whp from the Borla Attack system, aftermarket intake and a 96 octane tune?

    You mention that you are located in Europe, so your car may actually have the 444hp rating out of the box due to the compromised header design, or am I making the wrong assumption?

    No I'm in Cali but I'm from italy so I'm familiar with gasolime over there.
    My car seats at 465whp. (Oem was higher than 400)
    Now on top of the 15% more HP
    What is important is the torque you gain. Especially withban engine like ours that work over 4000rpm having a tq gain in the lower rpm helps a lot :)
