Been chasing a slight low rpm surge after header install and new intake, Halltech KBII. Installed stock tune. when cruising, stft swinging wildly, but off throttle, the movement seems reasonable.

The car has no exhaust leaks around headers. They were checked last night. At one time I did have a small air leak in Halltech intake but that has been addressed.

Appreciate any feedback. 02's only have 10K miles and were fine before header install.

Attached log is after trim reset.

STFT excursion is well within limits and looks normal... LTFT looks very good. :cheers:
