So I just finished installing my megan catback and downpipe and I need to reflash my stock ecu. If anyone does this please let me know. Also this is for an 06 wrx.
Not sure what you're asking. Are you wondering what the process is for reflashing the ECU, or are you wondering what exactly a tuner changes when "tuning?"
Yep, that will help too! I was just listing my next plan of attack, if I decide to drop more $. Mine spools up just like the stocker so no complaints from me
