here is the log from this morning
Looks like it might be misfiring? Does it feel like it is?

I saw a spot in that log where it looked like you were up to 3psi of boost or so and it was still in CL / not in PE. That would concern me a bit
No I didn't feel any misfires.
schpenxel - what would need changed? I know the car still has the issue that it wants to stall on first start. It should be within the first minute of the log this morning. Cold start when putting into gear. Doesn't do it at idle in park but when I put into gear
I'd try messing with min airflow. engine-->idle-->airflow. "Airflow Final Minimum"
If it only gives you issues at certain ECT's then you might end up having to play with the "ECT Mult" table right near the min airflow one to effectively increase it only for certain temps.
That's where I'd start
Ok logged a few more times. I added misfire counters since it was asked about just to check but nothing showed and the car ran fine.
One of the issues with the car is shown on #1 at 7:13:19 through 7:13:30. All I did was put the car in reverse at that point.
#2-#4 are from tonight after work. #4 has a harder pull on it but mostly just normal driving
schpenxel - you said at there was something that would concern you. What would you recommend that I change? I don't want to go in and start messing with things that I don't fully understand.
Are you using the MAF table Greg posted?
Fuel trims looked pretty bad in the first log I saw
yes I made the changes last night then I loaded it this morning before going to work. I flashed then logged #1
Well, I did say it was going to need some correctionsHere's the latest - still not going to fix the stall, but will help with fueling issues...

O yea I figured this wouldn't be a quick process!
Thanks Greg I will flash sometime this morning and go out driving and post logs when I get back
todays logs
You must have opened an old scanner profile - it's not logging any of the parameters you recently added? Can't make corrections unless these are in there

awesome... I added the ones that went missing and saved the file this time... Do I need to add(or remove) any others
PE throttle enable is 50. isnt that a little high for a boosted engine to enable PE? also how do you get away that much timing?

Add 1.5 to your minimum airflow table too like Carson suggested earlier - idle - airflow - base running airflow - airflow final minimum / see if this helps the stall at all? Post the stock tune too please if you have it... There's some things different in your tune that I'm not sure have been changed or just odd from the factory...
Yeah we need to fix the PE settings too - we'll do that after getting a few more logs...

ok do I add 1.5 to all the values on that chart?
I don't have the OE GM (pre supercharger) tune on HPT. I have it saved from a Diablo tuner that I had and its in a .grg format... I don't have anything to read it though. I do have the tune from Magnuson though. It wont let me post the .grg file If you can read it let me know and I can email it to you.
I logged for over an hour and apparently the file size is too large to upload so I tried breaking it down and saving sections but only one log saved all the data. This one was the second 10 minute block (minutes 10-20) but it has some cruising / stopped and idling and the higher speed run I made
Post your latest tune file - something isn't jiving? One log, fueling will be somewhat decent - make small correction then its way out in left field all over again...

its the 82716 file in the last post
I kinda noticed that. I said something to my wife about the fuel trims being all over the place (not that she knows what that was)
Next set of questions or question - your intake temperature sensor is now in the supercharger - right? There's quite a bit off in the tune - not going to sugar coat it... OH and did it do the stalling thing with the base magnuson tune??? Guess that's it for now...

1) Yes its in the supercharger. I did add the royal purple coolant additive (Purple Ice) to the supercharger cooling system yesterday - didn't really seem to do much but I only logged the one time yesterday.
2) Don't worry about sugar coating it, I didn't tune it. I kinda knew it was and that's why I'm here hoping you guys who know way more than I do can tell me what to change.
3) No it didnt
