don't bother with the omex unless your planning tb's, they've moved along way with mapping & should be able to map your existing ecu to cope with cams thats what i'm about to do with shrick cams, i had an omex & sold it as your looking about a grand to fit & map it on top of the unit which is £700 ish so your looking at between £1500-£1700 fitted & mapped & you could get your ecu mapped for say £300-£500 max. i'll let you know how i get on, pm me to remind me, it should be any later than late jan.
