lag/bogging due to fuel pump change?

[ESone3]

I have a S13 w/ sr20det redhead and I just changed to a 255 walbro intank pump and i've noticed that i'm bogging/lagging at the bottem end. Its really really slow. I have also turned down the boost, but I don't remember it being this slow at the lowend. Has anyone experienced this before?

careful u didnt connect the power to ground and ground to power. did you make sure the hose clamps were tight on the fuel pump? wanna check the FPR? seems ur running too rich on the low end. do u have a wideband or access to one?

i'm pretty sure i connected the wires correct. I really think its a ECU issue, but I just wanted to know if their is any downfall to adding a fuel pump to a stock SR setup.

there should be no downsides to installing a walbro on a stock SR, or KA.
