Had it mapped whilst it was on 95ron and now I have filled it up with super unleaded it seems like it's less responsive again under acceleration. Can't see how this would affect it?!

When I was driving around in it after the remap on normal 95ron stuff it was really responsive and the flat spot had gone at 2000rpm upwards. Just kept pulling! Since putting in super it seems to have affected it! 😳
