car starts fine and ok on low boost but will only hit full boost for less than a second then drops back and flutters at about half with no really power. has any1 else had this problem??if so what did u find?? as garage 200 mile away. have checked all boost pipe n clips tight, all ok. cheers w40ers

 

bump, just wounder if quick fix instead of heading down road

 

on a mk2 focus RS... i think they suffer from a pipe failing on the airbox side of things think its on of these u need http://www.focusrsparts.co.uk/focus-...t/prod_13.html, or just give them a call they know there stuff
