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?
