with my dashpot tune - I'm fighting IPC and surge under moderate acceleration, worse until the car warms up.
I'd been thinking, the dashpot tune is adding requested air (dashpot, preposition etc) that predicted throttle isn't accounting for, so I disabled all dashpot by lowering dashpot parameters, raising enable flow and vss. the last thing I did was enable oscillation switch, and desired air mass logic, the IPC at part throttle is still there.
What else could be contributing to this?
