I own a 2018 Mk3 Focus RS.. Its Shadow Black and I suspect I’m an amateur detailer.
I use it more for travelling to work on letting it go a bit crazy on the private back roads.
Recently I have installed the Mountune M 400R which I love.
However even though I will never have the full benefits I am eyeing the Mountune 500 hp next year…I should look at the M450also.
I enjoy the forum news and hope to glean some advice to aid my decision about the upgrade in the coming months when more feedback of the systems wil be present as im sure a lot on interested parties will have the upgrade done!!! I truly enjoy this forum
