Working on tuning my car and I've run into some problems, here is the low down.

I've tuned my VE Table to the best of my ability, along with the MAF tuning piece. Turned back on LTFT and STFT and...

Great news, I have my new exhaust and Wideband installed and working.
I'm sure there are different steps for tuning with the wideband, so where should I start since that was my crutch before?
...

Just checked mine out. It seems I don't have a vacuum line on the pressure regulator at the fuel rail, I'm using a stock LS3 intake manifold, I've attached a picture. There is no external regulator...

It's actually been surging the whole time, and the first tune I posted meaning the one I asked for help about last week? The first post?

Ok, those changes made it worse, the surging is louder and it's dropping lower in the RPM range during each surge. I have a fuel pressure gauge on the rail and it's showing 60-62 psi, not dropping...

Ok, got a run from cold to operating temp, with the IAC unplugged and here are the results. The IAC Seems to be working as expected, but please correct me if I'm wrong here. I pulled a fresh tune...

We did of tuning for this spark and from the data gathered previously it seems like it wants 26-28, so that's what it's at right now with overspeed and underspeed zero'd out, and as far as...

Ok, so I modified a few things that were pointed out. I went back and referenced the IAC Steps vs Effective Area and they were off from the stock LM7 engine, so I put those new numbers into that...

Murfie, I added 2g/s and it's still doing the same thing. Something else has to be up with the spark tables, we've eliminated anything else adding spark, do you think it's caused by the HO / LO...

Still seeing the same thing with those changes, I just had it cold and up to operating temp, and here are the results. The idle seems to be great while getting up to temp, but as soon it crosses that...

Got the throttle to show 0.0 after adjusting the idle screw while it was running and copied over all your values, it seems to be running a little worse now after zeroing out those over/under tables....

Got those numbers into the new Tune and wrote it to the car, it's seemingly better although still surging as it warms up. I'm attaching the Tune and the Log.

MixTune with your suggested changes...

I made those Modifications to the MAF and here are the results. It's still surging really badly. I did try to remove the plug from the IAC and that didn't help at all, I did the IAC reset to have it...

I'm really not shy about throwing a few extra bucks at something I can throw on and test to see if that's the problem. Can always return the parts if need be. I've done an extensive search for vacuum...

** I haven't cleaned the MAF before, so I'll go grab some cleaner and spray it out tomorrow, it could be something like that as I have no idea what kind of life this had before. The alternator is...

Still learning here, so bare with me. Underspeed / Overspeed correction was suggested by Murfie, and honestly I'm flying by the seat of my pants here, what do you mean by did I try +/- 8 degress on...

I see exactly what you're pointing out now, that makes more sense to me, it was just so chaotic that I wasn't looking in the right place for that Plateau.

Ok, so I took your advice from above,...

So here is another tune and log, I did your recommend airflow and it seemed to be hesitating alot while trying to idle, of course that's normal for this thing so far. I did another 50 to 1 step down...

I've set the PE to 1.2200 across the board for the time being, I saw your post before I flashed the 0 PE table and that was a very good thing. I haven't taken it out yet with the new changes, but at...

I setup my VCM like you had yours in the picture and I commanded spark from 50 down in 10-15 second intervals as you suggested. This is with the modified Tune with the changes you proposed. Trying to...

I've dropped the PE Table to "0" Across the board when I saw this, I do have a log with the previous tune with those specifics that were asked for. I'll flash the new tune with PE zero'd out through...

Murfie,

I've modified the PE tables a little bit and was hoping to run them by you, I pulled these from another tune that was close to mine, I think it's still a bit low but if you could take a...

Came here looking for some advice and to make sure my tune isn't going to blow up the car. Recently swapped an LS1 (LM7) into an RX8 and I'm going through the rigors of tuning.

I've scoured the...
