You need to have the ecu analysed by someone who can plug into it, normally a mapper will be able to tell you if your car has had the ecu mapped.

Is it running at 18psi consistently, or does it spike up there before dropping back?

If it holds that boost pressure, then, as Tony says, something is not standard, as the boost target for your car should be 0.94 bar - or 13.6psi.

As he says, you can have the ECU looked at by someone who knows what they're doing. Before doing that though, and on the assumption you haven't had this car too long, have you checked around the turbo for the presence of a manual boost controller, or for a piggyback device of some sort spliced into the wiring around the ECU?

runs up to 18 psi and drops back to 16/17 psi and there are no wires near ecu i think from what i have picked up so far mine has to be remapped and cant see anything from what i know around the turbo it all looks standard apart from new silicon hoses from turbo and inlet was told when i bought it it was chipped but anybody could say this he said it was 300bhp but like i say i could sell u anything and could say it was 500bhp just like to know b4 i spend any money remapping it have been conned b4 from an old cossie when i knew it was chipped and asked to upgrade my power only 4 them to say 500 quid as its not chipped at all so want to avoid.Any good remappers anywhere.

Do you know what's printed on the sticker on the top of the ECU can? What colour is the sticker, green or pink?

Hi it is peeing down here so i will send you a pm in the morning i guess it is the passenger foot well and i need to remove the cover.Thanks for your help oh and who is tony.

Splitpin

Yep, passenger footwell. Handful of plastic clips to release the carpet then four 10mm bolts (well, 3 bolts 1 nut) to get the cover off. Make a note of the colour of the sticker, and all the scrawl on it.

Oh - and while you're there look for anything connected into the wiring loom that doesn't look "original".

Tony in this case is Mr Burns from post #2.

Splitpin

That's the standard MY00 UK ECU. Was wondering whether you might find a PPP one in there but now we know.

Okay.

That sounds interesting. Can you see any maker's name or other information on this box, and can you see which of the wires in the ECU loom it is tapped into?

Hi all i have put some pics on my garage for anybody to look at and work out what is below the ecu one being wiring one being a silver box below and last the black box to the right of the ecu.hope this helps anybody to reconise.will go and see if i can work out where these wirs go.
