Decell?
 

Ok, idle is great, accell is great. But the car jerks when in low load situations, like low speed cruising, highway cruising (smoother with AC on), and cruising downhill. I have the BMW TPS but it seems to really jump some pretty big percentages, so that could be part of it. I am pretty sure that I need some Decell but I also don't want to foul out plugs (which I think was my idle which is much leaner now). Any suggestions on some numbers to start with? Something else?
