There is the kind of help I need without even knowing it. This scan I tried to follow your advice not easy with stop lights every 5 feet and every one of them red but I think I got some good ranges.
I did check the headers and they seem to be tight I found a couple clamps loose on what I think are the AIR pipes, the metal pipe that screws in to the top of the headers and goes through some valves and into the back of the intake manifold. but that does not seem to have helped the split.
I did forget to post my setup sorry about that. Yes its a larger throttle body not huge but a stock one bored to 52mm, I have ported stock heads with larger valves, Lloyd Elliot LE1.6 cam, 30# injectors, and ceramic coated long tube headers into a custom made 3" exhaust ending in stock LT1 mufflers.
Hi Travis, I looked at the 'cruising' part of the scans and there seems to be a difference in the learns between cells 3 and 7. This suggests to me that the VE tables could do with smoothing out a bit - you could try VE Master to smooth the lower RPM values.
Your idle actually looks pretty good (records after 3094)- maybe you did fix some aspects of the split?
Next step - try VE Master. Then progress to part throttle acceleration runs.
