87 GN, TE44, Exhaust, DP, TT Chip Front Mount IC, Alum. radiator , PTC 2800 Conv. ect.- I know pretty much everything about the car except what fuel pump it has. Pump gas, 17psi boost with AEM Air/fuel gauge the car wants more fuel. I have the max fuel dialed in and it still runs lean on big end. increasing fuel pressure make no difference at all. Any suggestions? no fuel leaks and no blockages. Thoughts are welcome and suggestions as to a new pump. Thanks in advance!!!
