Hi so I have a 2004 Subaru WRX that I got from Copart, a salvaged auction. The car has a few mods: srs exhaust, down pipe, headers, and sti tmic. Not sure if it has upgraded fuel pump or anything else because whenever I turn the key the fuel pump seems to be louder then it should but recently I bought a v3 Accessport because of the mods it has and I wanted to make sure it had a tune at least but I didn’t know it had a previous tune until I got the AP and I went ahead and installed it either way to stage 2 91 and my car runs like crap now, whenever I gas it the turbo spools up and down so I tried different maps but it’s doing the same. Before the tune the car ran perfectly fine so I went ahead and uninstalled the Accessport but its doing the same. What do you guys think it is? I’m not sure if I completely messed up the tune and I’m going to have to take it to a pro tuner and get a proper tune now or maybe I messed up the ecu?
