can pretty much guarantee that your hitting fuel cut putting that amount of mods onto the car without a boost gauge you cant see what your running firstly im selling a hks fcd if you want it £60 delivered pm me if interested. id also guess it might be running a bit lean if you have all these mods on on standard management depending on what boost your running at. id say get your gauges wired up, buy a fcd and then get the emanage on and get it mapped and fuelled correctly. then it should go like fuck and run very reliably mate
