here is the tune from the log....

Detected a small air leak.....lets see, what's next....

I fixed the leak, but the scanner shows strange things.
In the lower RPM it works fine.
At 3600 RPM it goes up to high values like 100 in the mid range.

Where did you find a VE table to start off with? I've been poking around for good initial values for a VE table but haven't found anything that I can use as of yet. Also have you seen any chances or improvements since you corrected the vacuum leak?

Just as an update, I did find a video on Youtube that assists with tuning VE tables for GM's. I'm hoping that when I get to this point I'll be able to use a lot of the information from it where it applies.

I started with ve table +20% to get it rich. now with the new intake the table is lower than stock....

Still the same problem.....Do I have to DISABLE the VVT to get off ANN on 2013?

Then I would get a camshaft without VVT ....Any Help?

yes you have to completely disable nn and the vct to have any effect with your ve table.

Thanks, but what more should I disable?

NN = Off
VVT = All set to disabled

I think I try to set the Injectors first with WB, maybe the difference is too big to get correct VE.
