Maximum number for torque in scanner?

[lt1z350]

When I am logging I have a table up for max torque just like to compare when tuning it makes more or less playing with timing. Anyway when I was n/a it never went over 320 ish. Now with blower I am seeing a max of 640. I know this is max as it hits this and logs miles of it from 4000 rpm and up. This is on a 2007 tahoe 5.3 with blower 12 lbs boost. What is making the limit? I ask as my trans is built up big time (build for a living) and it was rocking the 1-2 2-3 3-4 shifts at wot. Now my 1-2 hits like normal up till about this ceiling of torque. Rpms above it I think the thing is pulling pressure. I went into my 1-2 shift table bumped the stuff up and it doesn't help. It isn't slipping just made my 1-2 lazy when down on it making all that torque. The way it is built I should have no problems I know I need to get a gauge on it just starting thinking about this torque ceiling I hit and thought possible this was affecting my shifts up top. My tune is a lot of a 2012 zl1 and when I go to torque management in some torque coeff table I see the zl1 is a lot higher. Maybe I need to copy and paste all this over? Trying to figure out why to copy for blower and what I should leave alone due to smaller 5.3 and stock cam might be causing me issues as I now found out from an axis issue on my injectors. So started going over the tune and seeing what is still not the same and saw that and know all trans shifting is based on torque numbers so figured if that is skewed then can make my pressure go all wacked. Didn't put in trans area due to thinking not just a trans issue if I need to swap this table around. At work so don't have computer for exact table I am thinking about. And yes all my other stuff is maxed out that should be for torque management. Thanks

It's probably a limit either of Scanner or of what the ECM reports out. I've seen the same on some of the airflow #'s, depending on ECM it hits 512g/sec or 640 or whatever and that's the highest it'll display

Basically, this, except for torque instead of airflow:

i have a couple of torque outputs in mine i use "engine torque" it so far hasnt hit a limit but others can stop at the 640 ect

Gotcha makes sense. Guess only way to know for sure is look around for other supercharged e38 setups that have logs posted and see if they logged delivered torque and see if peaks the same. Thanks

Delivered torque reads to 640 on my E38.

Awesome thanks for response and bet it is maxed out pretty quick on that setup. Lol

the torque calculation that uses the airflow that maxes at 512g/s will limit to the 640, but the "engine torque" calc uses dynamic air so it will keep on going max i have seen is over 1200
