Benefits of a remap

[sonny]

Charlie at Surrey Rolling Road runs it in 3rd Gear, says it does not make a difference.

Sorry Steve, I should've mentioned that it was cleaned and ported. Can't imagine the porting makes a huge difference (?) but who knows with the cleaning! Either way it's probably clogged up again now but still feels much quicker than before.

Power went from 370ps to 431ps.

Sounds about right - I've had the same work done and mine went from 358PS to 434PS. Think the clean/port took it to 415PS and the filter/map the rest of the way.
