I think the RS EFi unit did pretty well up to 5k rpm. Infact it was slightly better in mid range, bhp and torque. Probably the flow rate having 90 degree runners let it down above 5k rpm?
Shame the Rover inlet wasnt tested.
What inlet was the Fiesta demo originally running and mapped to?
**Edited to mean the HO unit not the RS efi one
