I bought a 2010 civic si FG2 completely stock, i bought a hondata flash pro because from research you need that first before anything.

can anyone give me a step by step for the upgrades i can do over the span of a year or 2 one by one as i dont have enough money to dump 10k in all at once. i’m planning on buying a hybrid racing cold air intake and skunk2 headers but i need more things i can do 1 at a time after that where i can still daily the car. thanks a lot to anyone that can help!
