since ur ecu should b tuned when addding bigger injectors does this mean it also has to be tuned if switching from a ka fuel pump to a walbro?
Not necessarily, but Scott Avoy(Enthalpy) tunes differently for the walbro 255 pump anyhow. And he is right on the money with ecu tuning…
sucks that enthalpy doesn’t do CA18’s though… anyone know a place that can do it for a CA18? I was also looking to Horsham Development chips from the UK
