Peugeot boxer speed limiter

[Morgan 76]

Wondering if anyone has found the option to remove the limiter on a Peugeot boxer minibus 15 plate.
I have tried a few things to remove limiter but nobody is able to do it as when they plug in computer there is no option to remove.
It has a tachograph fitted and was told this may be the cause.
Can anyone help? Cheers

You might find it’s linked to the taco. Take it for a run see what the revs are flat out the disconnect the speed pulse and see if it goes any faster.
