I know my car basics. I am a noob to anything other than that. I do not understand this retune/ engine managment. But im trying to learn more about this and this site has helped me a lot so I thought id throw the question out.
Im looking to replace my stock dp with a ERZ dp and my uppipe with _____ (help with this here). Ive been told in other threads that I need new engine management and a retune. Now I dont know a THING about this. Ive started reading about Tactrix cables basically because I dont want to spend all that money on an accessport.
Im trying to get the wrx rumble Ive heard on many wrxs in my town, the pro-drive muffler just didnt do it for me and actually made it quieter
