Truck speed limiters will remain at around 56mph. The speed limit for trucks has been raised from 50 to 60mph on dual carriageways, it has always been 60 on motorways so nothing will change. Been raised from 40 to 50 on single carriageway roads. Many companies set their limiters at 52 to save fuel. You cannot easily tamper with modern truck speed limiters and garages are bound by law to report any tampering attempts found during servicing. A loaded truck will easily do 70+ downhill even on a slight incline.
Truck driving technique is to drive on limiter at all times so downhill they can achieve any speed the driver lets it do as inertia overrides the limiter.
Anything over sixty will be recorded as an over speed on a digi tachograph, and it will not go away until you acknowledge this by pressing okay, subsequently seen by your employer when the card is downloaded.

I have found the worst is car transporters, once you follow one of those it throws you all over it must be the turbulence the array of vehicles it is carrying produces, I try not to get caught behind those if I can help it.
It's the bow wave from large vehicles that causes the wandering problem.
The bow wave first hits the rear of the van turning it clockwise - the van then turns the car slightly anti-clockwise, so you are steered to the left.
The reverse then happens when the bow wave hits the front of the van.
Twin axle vans survive this motion slightly better because they have a wider pivot point.
Even better, a tug with a high car to van weight ratio.
