he tried Mountune's MP215 package for the ST. We needed to find out for ourselves.
So off I popped to Mountune HQ to see various Daves (the official Mountune collective term is in fact 'a wave of Dave') and have our ST tweaked.
Parked next to Walter Hayes' old GT40 and a 2004 GT, EX13EBD was swiftly stripped of its stock airbox, replaced by a Mountune aluminium item with a K&N filter. A laptop is then plugged into the OBD to update the ECU with the Mountune map. Ford and Mountune develop the map together to ensure the right combination of power and driveability, plus to ensure Ford are happy to warranty it. Everything is done within an hour, adding around £60 in labour to the £599 package cost.
in the USA, don't forget. In Europe, that figure can't be stated as the overboost isn't permanent.
The Mountune MP215 pack takes the overboost figures to 215hp and 236lb ft. What it definitely doesn't do is add 35hp and 59lb ft. Come on, it's a remap and a new airbox! Plus the badge, that's 5hp by itself...
It's a brilliant upgrade. Given an ST could be Mountuned for less than the cost of the Molten Orange paint on our car, it's a no brainer. The new airbox brings some extra aggression to the induction noise, and there are some additional whistles and sneezes when the throttle is lifted as well.
Moreover there's added confidence at motorway speeds too, the ST happier now to lug through sixth gear. Although, to be honest, I'm often changing down just for the enjoyment of it.
The Mountuned ST is with us until early December, in which time it should be reverted back to stock also. Then is perhaps where the difference will really tell. Wonder if we can get it dynoed before, just to make sure of those headline figures?
