    FSE fuel boost valve...YES or NO!

    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.

    Rich

    iirc these are only good if you know the amount of fuel is supposed to be used, for example:

    more air is getting into engine, but not enough fuel is being injected, so you uprate it or change it for a adjustable fuel valve to increase it.

    but increasing too much will also make the mpg higher and possible damage your engine.

    so i'd say go for it if you know how much is needed, but if not i wouldn't bother....... also free bump!

    as i'm sure i'm talking about something else lol hope someone else will come along and correct me :P

    If you have a cat forget it, as ecu will correct it all the time to keep correct afr, it will just adjust pulse width.
