hey mate. I've got a vipec ecu running my r32 GTR. Straight plug and play and im really happy with it. Wouldnt go anything else. Cold start is amazing, running 800cc injectors, big cams and doesn't miss a beat. Plenty of protection, fuel cut options, boost cut, boost control. Got 420kW at all 4 at 22psi. Lovin it. For more info call scott at insight motor sport in Sydney. Great tuner! Knows his shit
