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?! the electrical connector is pointing towards the engine block. any help or photo's would be appreciated.
