I think we will benefit from having the headers once we get into tuning. With the stock tune, we may have lost backpressure and lost a little tq, but once we are tuned and we are flowing more air through the system, we will benefit from the extra flow. Meanwhile those without the headers will suffer a little from the obstruction. I think without a tune, the stock ones are pretty dead on the necessary flow. With a tune, the upgraded ones will be dead on.

Yep, I agree. I don't think it's a fail at all. The results may be a little underwhelming, but I think that's just because we've seen such insane gains from all the other bolt-ons up to this point. But let's be realistic here. Getting +18hp from intakes is insane, and getting +11hp from headers, while not as impressive, is still a very decent result. Or to put it another way, if we feel disappointed at the results from the headers, it's only because we've gotten a little spoiled. I agree that we should greatly benefit from a tune, and we'll find out for sure soon enough. Sharif said that he expects UpRev to have their software ready for the 370Z in about 2-3 weeks. He also said that he estimates he'll be able to get another 15 whp out of my car. Time will tell!
