Mountune performance has brought out a performance upgrade for the zs aswell.
The engine upgrade, (quoted from website):
The Mountune Performance Fiesta 1.6 Ti-VCT engine upgrade is designed specifically for installation by Ford Dealers who have the diagnostic equipment to reprogramme the Engine Control Unit with the appropriate calibration.
The 140PS performance upgrade, for Zetec-S and Titanium 1.6-litre models, consists of a high-flow air induction system, a high performance exhaust system including high-flow catalyst and tubular manifold, and re-calibration of Ford’s 1.6-litre Ti-VCT Sigma engine to produce 140PS at 6750rpm and 170NM at 4250rpm. This boost in performance reduces the standard 0-60mph time from 9.9secs to 7.9secs.
These upgrades do not affect your Vehicle Excise Duty (tax) banding as they are fitted after vehicle registration.
Mountune Performance have tested the upgrades on British B roads and on numerous laps of the famous Nürburgring Nordschleife.
The 140PS kit can be fitted to any 1.6 Ti VCT Mk7 Fiesta, new or used, and has a minimum 12 months/12,000-mile warranty without affecting the vehicle warranty.
And they do an exterior styling pack, which looks like:
