Whilst with Munster in Barnsley today, we tried both a standard R and a mapped ecu, both of which worked absolutely fine with my car. No sign at all of the cough/splutter that my car has been suffering with at 3,500rpm, so I can eliminate the plugs etc.
Now to look at what I can do with my current ecu as I don't have a spare, or I'm buying one of Wayne(Munster), if one of his should become available. Thanks for helping me find the cause Wayne.
