I subsequently found out that I had a vacuum leak from a hose connected to the exhaust which resulted in power loss.

Yeah, it was the hose connected to the tailpipe. It was easily fixed by plugging the hose with a grub screw; I also did the other one; now the car is on loud mode all the time.

If you are suffering from vacuum loss the EPC light should of come on because the tumble flaps in the inlet manifold are also operated using the vacuum system & if they aren't opening properly it should log a fault.
