I recently performed a dod delete and cam upgrade to a BTR Truck Norris. I don't really think the tuner knew what he was doing with the gen 5 l84. Truck stalls when I stop at lights. Im looking for a base tune that I can build of of my self.

who tuned it? was it someone local?
Here is the tune file they put in the truck. It stalls when coming to a stop.
can you post the stock read file?
A lot of us on here tune for a living. I'm actually doing one of these with a rear mounted turbo and long tubes for a guy in Hawaii right now. These require more knowledge than just gen V's in general. Torque models have to match one another and all of the NN has to be dialed in for the setup...

These will need to have the idle fueling dialed in as well pretty close to perfect to idle right and especially when returning to idle.
Couple of things i saw in the file that we usually change when doing a camshaft.
You'll have to make sure the NN is dialed in properly as well.
Try this and see if it still wants to die coming to a stop.

if you want to message me a log of the truck I can see if I see anything. Just looking at the file I don't see anything that stands out crazy to me, but we all tune differently. It's really just going to be dialing in everything.
Again, if you want to shoot a log, I can see if anything in particular is sticking out that needs to be addressed.
You're missing a lot of channels to see main things when tuning these vehicles.
From what I do see, a lot looks great. You have some KR kickin in sporatically so I'd be looking in those areas as well.
I can't really see the airflow models without logging the VE and Dynamic.
Also need to be logging your IPW
here is a channel list to load into it and get another log.

It won't let me open it on my scanner. Let me try to figure it out and ill post a log ASAP.

Here is a log with the parameters you gave me
Looks really good.
There are areas where your airflow models need work still and are pretty far off from one another. That and the idle needs to get the timing up a bit. But you're moving on the right track for sure.
Build yourself some graphs to reference airflow error between the MAF Airflow vs Dynamic, as well as the VE Airflow vs Dynamic. Once the Airflow models are right, then start working the VTQ.
