Because it was shinny and a couldn't resist buying it lol I'm now in the possession of a tuning developments fuel rail. In my naivety I thought I could just whack it on there and it would simply aid fueling as I'm now running a Jam ECU but I'm hearing words like "wideband" and starting to think there's more to it, any advice would be sweet! My current set up is 4efte fm intercooler, tongs hybrid ct9, jam ECU, zisco mani and decat HKS actuator at about a bar.
