I am days away from buying my friend's 2003 24v vr6 6-speed Jetta and I'm looking for 300ish whp. Right now it has a straight pipe with no cat, I will be welding in a high flow cat eventually for emissions and plan to get a cold air intake or at least a pod filter. Can I run any amount of boost with a stock ECU/upgraded injectors? I would really like to get to at least 7 psi up to 10. If I can do this what injectors would you guys recommend? Input is welcome. If I can stay away from taking it to a shop to be tuned that would be nice I'm not looking for anything crazy. It also has 200k miles but runs strong.
