Saw that news today, surprising how little power we get in the EU market compared to US/AU. I imagine it's because there's basically no emissions requirements for trucks in those markets, whereas EU will be included in the fleet CO2 totals. Anyway, I'd be very cautious about just applying the other market tunes to the EU engines - although the part numbers may be the same, most manufacturers use different quality parts on assembly depending on the tune. The EU ones will have different spec pistons, rods and probably crank as well to save some money, so just applying the US tune which will be relying on better material quality for long-term reliability might not be a good idea. Obviously there's a lot of headroom in the tune, and I'd be very tempted to have it mapped, but I'd be very conservative and aim for more like 400-450hp rather than 500. Edit: I also agree with your stance on GPF removal - with the current science on emissions I'd rather decat something than increase the PM and NOx emissions in urban areas. I feel like we owe it to our neighbours not to poison them if we can.
Its been confirmed be a few different parties that the only hardware difference is the GPF... suspect the there just wasn't a case to change anything else given a relatively low volume of shipments in the EU. But good news none the less - the stock ECU is locked down so tuning options in lieu of anything officially sanctioned need an ECU swap, or a piggyback for mode modest gains - I'm not over the moon with the idea of the latter, but there are a couple in particular that have many happy punters on the forums.
This is why, if I was in the same position, I think I would be inclined to wait for Mountune, as not only do they work closely with Ford, their conversions/tuning don't invalidate the Ford warranty.
I hope to remain in a position of indecision for long enough for them to offer the package - that would be the best all-round option for sure. In the meantime I can make some more noise and pretend.
I'd be surprised if they are - I know from a production engineer friend that has worked with Ford, BMW, Mercedes and Renault all do it in various cars and commericals, even assembling engines in the same plant they'll be split into different market specs from the start. Anyway, it's a very minimal consequence unless you're keeping it forever
