hi guys
could you please check my log/tune and help me with these questions:
1. why afr jumping up/down when in wot. sometimes its 0.84 split second later is 0.76 lambda. Is it related to fuel pressure dropping?
2. bank1 02 reads richer then bank2. spark plugs look ok, i changed 02 sensors. Could be this further mechanical problem or this could be related to stage 1 camshaft?
3. your thoughts on the log in general.
