Thanks FOCA, I'll try a quick gear change to second - also coming from an automatic means a bit more adjustment.
We hired a new Fiesta diesel over in France last year and this had a bit more shift. Not expecting dramatic acceleration just a to be able to keep up with the flow of traffic!
Aside from a remap - kinda makes me nervous re insurance/warranty - is there anything else a little less invasive that may help with standing acceleration?
