What's going on here? When I hit the throttle while rolling at a steady speed it goes WOT, then closes, then re-opens. Its like bouncing off the rev limiter. I recall this happening years ago when the MAP got ahead of the RPM too fast, but I haven't touched the associated table in years. Whatever is causing it is not present long enough to trigger a DTC. I haven't noticed this behaviour from a standing start. Tried a tune from last year and it is still there. Only recent changes are a different 4L80E and converter. Just tested the functioning of the trans brake and noticed that the converter did not hold engine RPM at its rated stall speed(2600).
I have attached an edited log showing the throttle behavior. Another edited log shows the t-brake test(RPM climbs to 3700 before I let off the throttle), followed by the 2-step test(RPM holds at 2500).
I'm also seeing non-identical bank to bank injector behavior even though I have been running OLSD.
