Also I think once we get Uprev to gets us the 370Z maps we will pick up some nice gains from tuning it, the car is running rather rich around 12.5 plus we can add some timing

This is exactly what I'm banking on (hoping for) as well. My hypothesis is that without a tune, the headers are a complete waste of money. But once a tune enters into the equation, you'll gain more from a tune with upgraded headers than you would otherwise gain without them (i.e., stock headers).

The thing is, I'm getting more from my Dyno Dynamics numbers than RCZ is from his Mustang numbers, and DD reads lower than Mustangs. I think this is why RCZ is focusing on the Stillen HFCs, as that's the only difference between my setup and his at this moment in time (I have the Berks). The only other difference is that he has the oil cooler installed and I don't have mine on yet, but I doubt that's making any impact on HP numbers.
