I am running really lean too for some unknown reason...760C doing only 130mph pull on 18psi BPU. I have replaced Fuel filter, fuel pump, fuel pressure regulator, coolant, problem still not solved...
I am gonna go have my HKS AFR tuned next week and see what AF ratio I am running, maybe thats gonna help me determine my problem.
BTw, my fuel injectors has over 130,000miles on them, that could be it, though I doubt it cuz I had them out 20,000miles ago replacing its O-ring and they looked in good condition still.
it could all be the 91 octan bull shit gas we are using...dont know.
