    Hi Guys, i'm bit of a new boy on the forum and need a little help...please!
    I have fitted a new N75 J upgrade from the old N75, however have experienced problems when driving hard at around 3000rpm as if there is no power, then blip the accelerator, then pulls again. I have read somewhere previously on here, that the N75J is fitted in the opposite way round to the standard N75? is this correct or am i talkin out of me arse?!:tapedshut: the electrical connector is pointing towards the engine block. any help or photo's would be appreciated.

    See this image:

    Its not that you fit it opposite, it's that the electrical connection is on the other side so it looks opposite. All the pipes still connect in the exact same places.

    Also, knowing what engine it is would help...

    Make sure the longer of the 3 pipes coming off the N75J is going into the TIP, and then work from the pic. Just spotted your a fellow Gloucestershire member, where abouts you from pal?

    Yeah, more than likely, I'm always about Stroud, work there, the little one lives there, as do a lot of mates so often about! Small world. If you still have problems then let me know, I've got VAG COM you could use if this still continues to be a problem.
