No idea what it'll make it felt really good tho on 12psi. Im thinking about leaving the fuel pump and regulator for now so I can see what they can handle. Im planning to get a 550cc or 660cc injector to use as my staged injector which will be spraying on the inlet side of the Throttle body, this will also cool the intake temps a little too. Just a quick plug for George May Racing at Kunda Park top bloke!
