Turn closed loop back on and use the trims to dial in anything idle and part throttle. Leave the wideband for WOT.

"More cam" typically makes an engine less efficient in the lower RPMs. It does not increase airflow across the board.

Yeah it's kinda ugly. Who TF runs 32 degrees of idle timing???

Sounds like the system is under charged.

That makes no sense. None of those things are related.

So you intentionally jacked up the idle spark control tables for some stupid sound and now you're worried about why the car won't idle or return to idle properly. Got it!

It would seem logical to...

Laughing at "installs lumpy cam and complains about minimal bucking".

What are "other various mods"? Crank up the BRAF til it idles. You'll probably have to reset it later when you get everything thing else dialed in but if you add a bunch to your BRAF it'll probably...

Holy shit you ain't kidding. +/- 35 degrees @ 16 RPM error. WOW that's gotta shake the fenders off the car!!

Both axis are editable. Click on "engine speed" up at the top (your X axis) and this is what you'll see. Clicking on MAP on the left will allow you to edit that axis.

There's at least a dozen things that contribute to your idle. It could be way too rich at idle. The idle airflow settings could be incorrect. Could be a variety of things or even multiple things...

Need a tune file and data log. No way to know what's been done, what hasn't been done, what's right or wrong.

Otherwise, this is what we're working with.

That thing needs more BRAF and I'd put the throttle follower back to stock. Oh yeah the VVE need work too. And need to know the cam sensor code number to help diag.

Yes but if you want to flash a completely new file to your PCM unless you have unlimited credits you will have to license the new file to flash to your already licensed PCM.

That depends how you want to approach that. But flashing it back to stock won't fix your split fuel trims. I'm telling you that's not something that can be fixed by tooning. Put your laptop and...

Do you have a fuel pressure gauge on the vehicle? Have you tried starting it using spray? Starter fluid, carb cleaner, flammable brake cleaner, etc.? That would be first thing to try.

Crazy as it...

Kpa sounds about right for your elevation. If someone previously tuned it for the MAP being off, you'll have to undo what they did.

Except for the fact it's at least partially incorrect. More camshaft equals less vacuum at lower engine speeds. Always.

Never mind. I just read it in that jumbled together paragraph.

Where did he say it had a FAST intake on it?

Nothing about that data log screams vacuum leak to me. The dead giveaway is usually the MAF Hz. Even if you "tune around" a vacuum leak it will idle...

Your pid list is terrible. Use the attached channel list for data logging. If you don't know how, search how to download, save and open a channel list.

Bank 1 fuel trims are pegged positive which...

Well, judging by the wealth of information you've provided, looks like it has split fuel trims. If the ONLY modification to the vehicle is a BTR stage 2 cam, looks like you has some problems.

You...

Wow that thing makes ALOT of vacuum LOL

Agreed ^^^ No reason to use anything but AC Delco or GM OEM.
