First of all REMOVE and REINSTALL your sotck fuel pump. That fuel pump keeps it running rich. If you have your stock I/H/E i would put them back to help pass.

 

well the stock uel pump was for a ls I now have a h22 i have the stock headers and i going to try to find a short ram intake they want too much for the intak ehere t the junkyard.

 

When i was running that same fuel pump the pressure was 51 psi w/ stock FPR, and then i installed my stock one and went to 40psi.
