I have been working and working on this tune and thought I had it as it pulled pretty decent for what it was esp. when 3rd gear came around. This was when I was hitting an 11.0 afr. But as you see it would KR bad! Autolite 103's gapped at .050 didn't even help so I put back in my 104's @ .050. So I had to add 2% of fuel from 9500 up and as you see the KR went down drastically (this was within 15 minutes of the last) so same conditions) but it does seem slower. What can I do now to help? When I was not ICed I tried 11.5 afr but was only able to run 11* timing. Put back in the old tune and was hitting 10.6-10.4 @ 17* virtually KR free on a 3.4. A 3.2 it hated unless I dropped another 2* timing.
Now we are a 3.0 Pulley ICed with a 10.9-10.6 afr @ 18-17*. The wide band is .1-.2 off so subtract that of what you see.
The screen shots are right when it goes into 3rd. Which is my problem area. Guessing the pistons are still getting toasty?
