An update on where I'e got to. Over the last week have been putting in BP Ultimate and now seem to get far better response than on V Power, still not 100% but alot better. Went to see Duncan @ Hypertech for a chat and a drive and he was convinced that there was not too much wrong but possibly that the ECU is relearning its settings and this might take a while. If its not improved in few weeks its back to Duncan for an AndyF remap as he says the std PPP ecu is just an off the shelf map and is not mapped to the car. Need to get out this weekend to see if I can help the map find the right settings.
Cheers
