I have an 03 evo with basic stuff done to it AMS cat back, DC downpipe, Injen intake, forge boost controler, and I am getting a reflash and dyno tune in the next week. I wanna do some more stuff nothing crazy prob wanna spend around 1500-2000 more and call it quits, What are some recomendations for things to do, More bang for my buck. and from that what do you think the HP - torque gain will be?
