Supersprint headers + a tune to make use of it (Evolve?) might get you closer to 270, but then you're spending around 1500 for ~15 extra hp. The $/hp get's a bit steep at that point for this mod. This is why I think that the DISA intake + AA tune + lighter wheels/tires is probably the most optimal power increase for our engines. Anything more than that is just sinking too much money for the gains.
