I'm sure Stu@MSD could do the software for far less than a new ECU

You don't, remember these kits are for kit cars, so won't need all the stuff the ford ECU will do.
I've basically bought the 170 kit, but It's been mapped on the standard ecu by Stu@MSD
170bhp in a kit car remember, doesn't have everything a fiesta has running off the engine! It's been said it should be about 155-160bhp on the Fiesta, but tbh I'd be happy with 140bhp!
Revs to 7600rpm too.
