Why? Unless you're changing parts that require tuning in between a single custom tune is all you need.
My general point being it seems silly to jump through the hoops and expense and not go the last mile for a custom tune out of the gate.
I have an early unlocked '21 so I don't necessarily have a dog in this fight. However... Why go through all of the trouble and big $$ expense to end up with an OTS tune...!? :dunno:
Not arguing that yours reads right or wrong, just in general MD read however they're calibrated, and they can be wildly different (as referenced by the post I quoted).
I would love to hear how you can cheat a DJ outside of correction factor. :hmm:
Nice start! How much boost? Would be nice to see the whole graph.
This is the problem with MD -- they don't read "low" or "high" or in between they read however they are calibrated. Great for tuning but it's impossible to reliably compare not only against other dyno brands, but even from...
In my personal testing with basic bolt-ons the stock "tune" has trims comfortably sufficient up to E30 - E35. In controlled conditions (don't try this at home, kids) you can push it in to the low 40% range before it will max the trims and eventually throw a lean code.

This is Map 6 working with Jesse but I ran out of time before we were able to get it fully dialed and the boost turned up. Improved the 60' a lot but between the DA, heat soak due to staging lanes and some other excuses I did not improve ET or MPH. Then the summer heat set in...
