I'm going to have to pay attention to my boost gauge while in launch control, see if it builds more than 2 or 3 psi.

electric NLS > Vacuum controlled NLS. I’ll take a video next time I’m out at my car on launch control, I could build 20psi on launch if I set it high enough. I’m starting it at 4k rpm and working my way up

So this is assuming the OP installs the 2.0 LNF 5 speed and computers in his LS/LT.

TMAP? Wide band O2 sensor. Where is 80Lb fuel pressure coming from, stock pressure is well below that.
Right forgot the manual trans doesn't need TCM.

So basically you are agreeing "cheaper and easier to buy an SS". If you want a 5 speed find a Saab trany and junkyard shift mechanism.

OP would be better off to not use the LNF and build the L61. I’ve seen L61’s make some good power. There wouldn’t be any problems with harnesses or computers then

So L61 with the LNF head to handle the boost and provide the DI and the HPFP?

80# fuel per hour not PSI

no just the L61 head. Just port injection. Although an LSJ head would be better if you had one available. Either are good with some porting, springs and cams. My tuner has a turbo 2.3 cobalt making more than 600whp.
