05 CTS-V with 80E Swap stalls going WOT from idle

[Hippo]

2005 CTS-V(P59 ECM) with a built 4L80E swap, segment swap from a silverado 2500, LSA blower, 1050 injectors and a 3000rpm stall. It wont allow me to gradually or abruptly get up on the converter, it will fight me at 800-900rpm and will not surpass that until I get rolling. If I try to floor it from idle it dies when it's in gear. The car doesn't have a neutral safety switch if that matters, it thinks it's always in drive. There are no brake torque or fast torque exit parameters in the torque management sections of this ROM.

Is there a brake torque mngt in the systems options?

[Hippo]

Yes. I turned that off and now it will come up on the converter from a stop however it will still just die if you try to abruptly punch it from a stand still.

[5FDP]

Post the tune.

[Hippo]

Here ya go

Is that injector data right? 1050's are only 100lb/hr at I assume 3 bar pressure and like 12% higher at 4 bar but the tune has flow rates at 130+. Just curious is all because that seems wrong.

Is your timing being so low down at 5 degrees a possible cause?

[Hippo]

Yes, the car runs close to 4 bar fuel pressure so the flow data was increased to represent that. I was leary to add timing down low on a 93 only PD blown LS6 but I'll bump it up and see what changes.

Did you notice that the converter completely locks up when you go WOT?

Not enough data to really tell. Could be the LSA going insanely lean on a tip in, as they are known to do. Could be the low spark not able to keep up with the blower load and causing torque to go negative. Could be whatever is compromising the torque before you even hit the throttle to kill the engine...an LS6 shouldn't idle in gear near 90kpa, throttle at max idle capacity...
