Carbon8 Build

After re-gapping the plugs it only happens very seldom and only in 4th gear and up. I noticed that during it my A/F dumps below 11. So Im just going to wait on it until we can finish tuning, and not romp on it.

Looking for some input.
Couple days ago I started getting hard hot starts, and white smoke out of the exhaust. Long story short Cam recommended Porosity tabs, after I used the tabs smoke went away. Now today the smoke seems to be back. I realized my hard hot starts where a tuning issue, and is all straight now no it starts and runs great but I am still getting white smoke. I have not driven the car at all, Cam recommends I put 100 miles on and see how it effects it.
Stats;
Coolant system pressure test held firm at 20 PSI both cold and Hot
Oil sample sent to blackstone today for testing contaminants.
Plugs cleaned
Idle Log
A/F 14.41
STFT range;.24-1
LTFT: 2.97 (constant)
MAF; 5.5 g/s
MAF; 1.23V
Ign Tim Sep; -15 degrees
Only thing out of the ordinary is LTFT, other than that the car runs great!
Here are the idle videos, the after video its faint but you can almost here what appears to sound like deep puffs (you can notice when the smoke is abruptly pushed away)

Misfire Subsidiary
Instead of making a new thread I am hopeful this one gets enough attention to help.
Been suffering a misfire since my rebuild, at first it was audible during 4th gear and up pulls only over 7K RPM under WOT. No flashing CEL no codes, just audible popping noise.
I re-gapped plugs and reset NVRAM, this solved the problem for a couple days then it returned.
Next I pulled the wires off the trailing plugs, to ensure that the leading coils are in good working condition. Car fired right up and idle was normal, so I do not have a leading plug problem. Also re-gapped a little lower as was recommended by Cam at Pettit.
So now the popping noise is gone but my new symptoms.
Only happens in 4th gear and up; Runs really rich at 4K with 20% load, 11.4-12 A/F If I let up the throttle the needle will spike down to 10, sometimes it will also cause a flashing CEL. No noise, no hesitation just a flashing CEL. I noticed my cruising A/F is more around 13.4. Doing logs my ignition separation goes for -15 to +5.
Running BHR coils (on OE Dwell), NGK plugs Gapped to .033, 93 Octane fuel W/ 4 oz Protek-R per tank, SOHN adapter with protek-R reservoir OE OMP rates.
Also want to add, I know 14.2 is peferct for little load and cruising, for an NA 8.
What is considered to rich, what is considered to lean?
Thoughts/Suggestions?
Go!

I would just like to say, I came across this little tid bit today. Will be testing my system as soon as I get this built either today or tomorrow.
Thanks Scott, and the SARX crew for mocking this up.

Yeah, Im gona run to party city, they sell it for the same price as amazon and I don't have to wait till shipping.
I fixed one vacuum leak last night off my VFAD nipple, but I can still tell I have another one somewhere. Progress is progress i suppose.
Guess this is what they meant by projects are never finished

First fogger run showed the MAF sensor was leaking in the AEM housing, need to fab up a canister before the nozzle as I am having the same problem of excess fluid in the fog lines.
Hopefully get this all straightened out this afternoon for some weekend fun.

what did you change in the tuning to improve the starting?
what do you mean fog lines?
what are Porosity tabs?
are you sure the white smoke isn't condensation or something to do with the air pump.
told you the dwell would help!
