ok guys injectors just got deliviered YAY, and as for what your saying i have also changed alot of other stuff with the fuel system like there was a few big kinks in the lines replaced the vl pump replaced the lift pump and i moved the filter cause the poor little lift pump was trying to suck through the filter. and as for pressure at the fuel rail i just clamped the hose on the reg and it shot up to like 100psi. also just spoke to the tuner he said he was 650-700 for another retune so does any one know any cheap tuners in gold coast brizzy area
