Tuning

I am looking at getting the Cobb can flex fuel upgrade + fuel pressure kit for my 2021 wrx that Mig tuned back in 2023. I have not added any other mods, and have no plans.

1.Which tune plan should I order?

2.Should I get an upgraded fuel pump if I don't plan on adding any other mods?

3.Does my old maps get reused or are they useless after the flex fuel maps are created?

So I’m starting the tuning process with the man himself mig and I kind of forgot to put my car on sport sharp, is it the end of the world or should I be good
