I have a early 04. Trying to see what people suggest on my next mod. Of course im looking for better fuel economy, and maybe even some more power. As of now- edge juice w/attitude. MBRP 4" exhaust. Airaid intake system/filter. and methinal injection kit. I was thinking probably injectors or turbo next? but wasnt sure and dont know to much about either one yet. Any info would be great.
