That's interesting. I would have thought it would have been pretty close right out of the box.
I'm local to them, so lent my car to them for a couple of months (back in 2016?). They ran a bunch of pulls, fine tuning it with the goal of having an ECM to sell to LT-5 owners. I got the car back from them with the MS3-Pro ECM installed and I haven't touched it since. It runs great. My engine is stock (including secondaries) with headers.
