Thanks for your comments.

I first learnt about it from a Fiat (old Alfa) garage where I took it with the initial fault. You will need to excuse my lack of technical jargon here, but the service dept told me that car had a new non Alfa chip fitted. My understanding is that this was in place of the factory chip.

They told me to find out who had initially installed this and go to them for the problem. Unfortunately, the dealer I bought it from were unable to give me a current phone number for the private seller they took car in p-exc from. All I know is that the car was previously from Sussex.

The garage told me that although they could read the error message of a turbo boost spike, they could not make any changes to the ECU chip programming because it wasnt the Alfa chip which their software could change.

Car needs an MOT shortly, and I have that hissing noise which on here suggests the turbo hose compromised. I will ask them again to give me any info they can, eg marking on the chip to see if I can then identify the source.

I am here in Nottingham, so if anyone knows of local Tuners etc that might be able to help, even if not their own chip, then please let me know.

Thanks to all who have offered advice. Really useful.
