It's time to get tuning the ECM in the Indy. I have some cold start issues at present.
So I was on the pcmhacking website and found this turbo-Duke S10 "rat".

He's running the 1227165 ECM with $12P code like I have on my GT and Indy.

Not sure if it's this truck, or another turbo-Duke project.

Of course what they don't mention is that it blew up at the end of it's first smoke-show.

With all due respect the Duke is not a good platform for Turbocharging. The S10 version has a bit stronger block but there are still limits to what power can be developed with those smallish rods. IMO anything over 4-5 psi of boost is cutting it close and even with a fresh engine a 4500 RPM redline is about it. . That might get you 130HP or 2.8L V6 performance. Is it worth it? Only you can decide.

IMO, if you turbocharge a Duke, you should approach it like a turbo-diesel. Set it up for low-end torque, and don't rev it past 4k RPM.
