It appears to be more of an electrical issue then a tune issue. And it much different then the last log that you posted. Note how both the RPM & O2 values are jumping around.

Check the EFI harness grounds on the back of the heads. Along with that the battery cables are tight.

I will do it, I noticed that the log also as far as varying rpm. And the bog is worse than it was without any changes. I'll check them
