Recall Campaign-ECM may not illuniate MIL on automatic trans malfunction

So I just got this notice in the mail. Notice says they need to reprogram ECM.
They will not find out about an overboost condition in my car when they reprogram, will they? I have the JB4.

Thanks.
Again, this means 4.0 psi peak over stock so I'd just put a 5 in the 2,500-3000 fields in my case. (Just making sure I don't blow it to pieces :))

I'd think more boost right around 2K rpm's since that's where it seems to stall at. But of course I do not touch my JB4 unless I'm specifically directed by Terry. I'm still new at it.
And at the...

This was probably already answered but is there a chance that you turned the ignition on while you had the map sensors unplugged? This will trigger those codes even if engine isn't running

Now, if it's not enough load, wouldn't it be not enough load on stock boost? Or are you saying it's possible that stock runs are just enough to load it properly but not when adding 3 more psi?

2 more runs at 3psi

First graph DWP at 30

Second graph DWP at 15

I honestly can't say the car feel super abruptly going up the RPM band when DWP is at 15 but it's more at partial throttle where I feel it. Is that...
