My truck was originally a 4.3 with a 4l60e I did a 5.3 swap with a built 4l80e. I have a wideband but wont be able to log it until Thursday. I am having a crazy amount of misfires despite what my log says. Can anyone take a look at my tune and see if there is anything glaringly obvious that would cause a gross amount of misfires?
The only mod is a BTR Stage 2 Cam other than the 4l80e.
