Should have got a certificate with the car ideally. And it would have pro drive silicone pipes from the intercooler.
But get it on a dyno, that will tell you. Should see about 260bhp give or take a little.
Hi mate, welcome.
I think the Maltese ones came with no alarm.
If that's the case then get an alarm / immobiliser fitted.
And obviously for insurance purposes it is an import, so they may charge you a bit more.
