Tweaking the rebuild. Rtek 1.7, 550 cc running rich down low.Fuel pump resistor relay

S4 N/A -> TII swap using N/A harness.

Hey, I've got my rebuild running and holding a nice idle at about 1k rpm. I've been runningt it in my driveway for a week now. I noticed yesterday, when I turned off the car using my fuel pump cutoff switch, the car sounded twice as good, 2 seconds before it died. I think the car is running super rich down low, and I think it's because I don't have the fuel pump resistor relay installed. Could I be overwhelming the motor at low RPM because of the full voltage to the pump? It's a walbro 255 fuel pump, with 720 secondaries and an Rtek 1.7. Streetported motor

Ok, new question. Is there a connector on the S4 N/A harness for the fuel pump resistor relay?
If it needs to be hard wired, I could just reinstall my Super AFR and lean out the low RPM's instead couldn't I?
