I dont know the stock FP so If someone tells me fine :)

Specs, Aeromotive FPR, steel braided fuel lines, j tube block off (suprasport kit), stock injectors, walbro 255, apexi filter an 2.5" exhaust line, im getting a 3" soon.

I have noticed since I installed the FPR the car gobbles fuel like mad, and I might be running very very rich, I thought wrongly from what I have readed searching that the injectors where the ones that put the fuel needed I dint know you could alter this with more pressure, so probably my car is running way too rich hindering the performance, I dont have access to a WB so im a bit lost here untill I go next step in my mods.

Can someone help me out here?

so what you're saying is:

1. you have an AFR but do not have a gauge?
2. you have a number of mods, but no WB?
