Thank you Oilman as you have confirmed my experience with oftec certified people and the last one i had here i had to tell him to leave as he was just fitting parts for fun as he didn't know what to change next and thats when i thought i can do that for a lot less money and sell them on later if they don't work.Waiting for an EBI unit to be delivered and then we can think about getting pressures set etc but it has run ok since i fitted it 20 years ago and i set that up by eye then.Nothing wrong with that as us old mechanics still tune cars by ear and eye and something young pups can't do.
