Intake + Exhaust stock ECU, rich or lean?
Probaly rich, but once you get all your mods on I would tune it. Its not gonna like blow up if you don't tune it, it will just go from being fast to INSANELY fast. I just got tuned, and my car used to pull hard, now when i drop on the gas it feels like i just hit by a fraight train. I swear Its a huge difference. Like Realy huge, and its starts pulling earlier, and to me the turbo spools a little quicker. So you get the long hard gut wrenching pull.
