224/230 114 --> overlap @ 0.050" = -1*

That cam should idle very well on the stock tune, and should have good low end torque... post the tune file that produced that log.

That log shows your NBO2's riding high always (i.e. too rich)... the MAF DTC tells me you're in SD (even tho you get a MAF reading)...

Do you have CL/trimming enabled or disabled (it looks like disabled)...?

so try bringing the VE down a little (highlight small sections of the log, and find where these are on the VE table (use Runway Highlighting)...

Cl trimming was disabled. I enabled it and hope to do a log at lunch time. It does idle pretty well after some playing.

Ok so this may be a stupid question but I don't want to regress, If I use runway highlighting and watch the narrow bands and my wide band and they show lean, I should lower my VE table in that frame to lean it? (A small amount at a time of course)
And as always, thank you for your time, Joecar.

Awesome, thanks again for your help. I know that every forum I've read you have provided guidance and insight so I appreciate all the time you spend doing that.

Do my VE numbers look low for a cammed 6.0 with 317 heads? I'm out of ideas and ready to pull the timing cover off to see if my timing chain is loose.
