Do you have posted somewhere why you went with a Supercharger in addition to the turbo? I won't bore you with reposting if you already have and / or have learned more recently.
I'm just looking at the HP the supercharger takes (which isn't anything near a 50HP 6-71) as compared to its benefits once your turbo is spooled up. Then at that point is the supercharger restrictive.

The sc isnt restrictive, its basically an airflow multiplier. It creates more exhaust gasses down low to help spool the turbo and after that its just along for the ride basically. At no point is it a restriction though.

Got an 07 2.4 SS Automatic harness from a junkyard. I deleted all of the auto stuff, AC stuff, rear O2 sensor, etc..




Finally got one of the blue body side connectors for an LE5, all labeled here

Disassembled my original body side connector (07-08 L61 and 08 LE5)




Lucky for me, since the harnesses are both 07, the wire colors and circuit numbers are the same. So once i took the time to label everything, all i had to do was depin the LE5 body side connector and replace the wires with the pins from my original body side.

Did you go over why you are having to adapt a different ecu or what exactly are you doing there? Sorry if I missed it.

I didnt like how it was set up before being an 07 car but overlaying an 08 file on the computer. It always had weird issues with engine power reduced and stuff. Plus i just wanted to see if i could do it, pretty straight forward actually. Hopefully it will run better than ever.

As long as you can keep the motor running for more than 100miles you'll likely find out

I'm all for you getting knowledge on swapping ECUs. Me being an 06 base model that is something I need to seriously consider.
