Default SMC changing fuel curve too quickly?

I have been running the SMC for a few months now and it has always worked great except for this one little problem. When I am barely on the gas, like in traffic in first gear especially, the car will jump forward and then nose dive constantly like I am punching the throttle and then letting off completely. Is the SMC changing the fuel curve too quickly up and down or is my stock fpr causing too much (or too little) fuel pressure on the DSM 450 injectors? Does anyone else have this problem?

Might be your TPS sensor? I don't think the car jumping like you tapped the gas would have anything to do with fuel delivery, but who knows...

Is there any real way to test the TPS besides breaking one off of another throttle body and trying it?

Anybody else have this problem? I'm also using a Walbro 255lph fuel pump.

I have the same thing. It almost feels "snappy" and quick. I believe it is normal...
