2014 Silverado low idle timing, starts easy but dies, wants to run 1500rpm in gear

[Lakegoat]

DI with 30% lobe, 234/248 cam, 30% over FIC Injectors, 408CI, Magnuson 2300 blower
May have to start 3 times before it will idle, any attempt to rev it makes it die as soon as pedal is released.
When in gear, as soon as you start driving, coasting, it likes to idle along at 1500rpm until I press the brake and hold it. Then it idles great. This is an idle log, look at the spark when I slowly get on the gas. I just need to get the startup and idle fixed so it doesn't take so long to get going.
I don't know beans about a gen 5, all the torque stuff. My son's truck, not a customers vehicle. I don't tune anything except my vehicles, none are gen5.
I did add 2% to the MAF 1 up to 3000hz. This truck has been tuned on, hacked on, tuned on, but never finished.
Thanks for any help

That tune file is jacked in many ways and his ^^^ didn't address any of it.

I am assuming that he has all the modifications well addressed

You'd be assuming wrong. Look through the file.

I'm not sure why you'd go making changes to his file without first looking through it.

Look man, that's just how the Instagram tooners do it these days. Get with the program.

I looked on the internet for a solution for a jacked up tune. There was a pic of my tune with "Don't touch this"!
The truck is in the shop getting the 6L80 trans rebuilt with some nice parts. 172,000 miles on stock trans. I do need to send this to somebody that does gen5's so it will drive like a semi-normal vehicle.

Just a FYI. That one started life as a 5.3 with a 390 OS. This means there's lots of things that have to be done slightly different when compared to newer ones out there. You need to add a sciap, BUT unlike the 15 and newer there's only 1 SCIAP table. 15 and newers have 3. There's also a background activation switch for it to work on top of the main sciap setting switch. You can get with Will_974 to get these installed into the cal if you wish to tune it yourself. It will most definitely need the sciap as those in particular are more touchy with the throttle operations. The injectors can cause their own headaches as those can be pretty hit and miss on flowing right. You can start with a lt4 torque model then work and modify from there.

AND then yeah, you really need to work on the rest. You got darkwing ducks head for a ve table, a flatlined soi, a worm MAF table and that was all i looked at

There's several folks on here that can fix it right, a couple of them have already chimed in here.
