Hi all, ive got an astra g 1.6 16v SXi. Ive derestriced the airbox and fitted iridium spark plugs. I was thinking of fitting a fuel boost valve next. Is this a good idea or not?? will it give me better accelaration? and how badly will it affect my feul economy?
Or how about fitting an adjustable fuel valve, would this be a better idea?
Or just leave it as it is?
Thanks for any advice.
