Though don't know if it will show up in dyno, it certainly should in real driving.
P.S.
You haven't mentioned, but imho worth to install also aftermarket dropin airfilter, if you haven't already. Should be cheap.

The first dyno was filter and stage 1 tune.

This is the exact reason why we always conduct our before and after numbers on the same dyno, on the same day, to try to keep those other factors as unchanged as possible.

Bottom line though, your numbers are up, that matters more than anything else.

Best of luck with all your projects!

Same dyno, same weather.
