Ive just fitted one of these to my car and ive got 2 say im mighty impressed!!
it sounds beautiful with my janspeed backbox
But my fuel consumption has dropped to the low twenties? does the ecu recognise the car is breathing better or is there someway to reset it?
i dont really know what im on about tbh! but i thort it was a bit of a dramatic drop!? y is this and is there anything i can do to get it back up a bit (except drivin like a grandad)
