Rb20 with a r34 turbo, FMIC, HKS pod, adjustable cam gears set at +3 inlet, -5 exhaust, split dump, about a 3 1/2 inch front pipe to cat and a 3" cat back, running 10psi. I would have thought with those mods that the standard fuel system could cope, but its leaning out on full boost. I have got myself one of Newkleer's consult units and its telling me im hitting 100% duty cycle on the injectors. Air flow meter is no where near the 5.1 volts for R&R so what else could be causing my injectors to hit max duty cycle?
Seems im about to upgrade rail pressure, although i beleive the rise in flow is not lineal with pressure, meaning a 100% rise in pressure only gains around 40% rise in flow through the injectors.
So what would be my next step?
