After I had the fuel map sorted out I was still getting some occasional "stutter & pop" during acceleration. I started watching the O2 display and the handheld LED's closer, and what I found was that I was going lean when I hit it, but it recovered within a second or less. The map was good, but my "accelerator pump" curve was too lean, even though I had steepened the curve a bit, maybe 5% earlier in the day. I picked up that handheld unit while on a test drive, dialed it to "Transition Fuel" and added fuel until it stayed just below mid 14's on throttle action across the range - I could not believe it wanted 20% more fuel in transition! Backed the macro correction out of the handheld calibrator, and went back to the curve on the laptop and added 20% through the idle and mid-range and the stutter & pop was gone! HOORAY!! Today Edelbrock sent me a new Crank Fuel curve to try, and that seems to have solved my starting inconsistencies. Now if I can just keep my hands off of those curves......
