OK. I got the fuel pressure attached to the rail, 67psi at idle. This pressure is needed for me to run a higher rpm before going lean. If I back off the pressure it goes lean at 5300 in 3rd gear. Ebay vendor sent me the same 450cc injectors in an exchange deal. I cannot run a decent afr with the stock injectors no matter what pressure I run and running a good afr for power sends the motor into lean land .Frustrating! THX!
