Hi guys, having a bit of a problem with my 02 Bora.

Got it remapped back in June/July of last year and was going great until the top intercooler pipe blew off. I have secured it but also noticed that the bottom one had blew off as well so I secured it too.

Was getting 45-50mpg until last Friday. Now I'm lucky to hit 40mpg but when I floor it I can hear a bit of a hissing noise coming from somewhere.

Can anyone give me any hints as to where it could be coming from or any other reason as to why my mpg is so low. I know looking at other peoples mpg on here even at 45-50 it wasn't great.

Please help as I can't afford to throw diesel into my car at the price it is and the mpg I'm currently getting.

Thanks in advance

Davy

Boost leak somewhere?
Check your turbo pipes if you can.. you might have a split/whole or another pipe could've blown off!

Where are the turbo pipes? It sounds almost as if the noise is coming from the centre of the car down and behind around the gear stick area and I can only hear it once the turbo is kicking in?

Hope I've explained this ok.
