Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

chuckd05

I believe you 100% , your customers satisfaction is outstanding, and your loyal fan base is really unmatched from anything I have seen on forums.

You seem to do research on a level that many other people/companies do not do, and I am not trying to dis-credit anything you are saying...

Its really going to take a few people who have money to burn to go the extra distance to have a 370z with full bolt-ons. Tune the car. Than Swap stock box back, tune the car again, than dyno again. And share the outcome with others.

And other people also need to follow the first person to do this , and once 2,3,4 people see similar results than people will start to believe it, whatever the conclusion ends up being.

I would not be all that surprised if it was true but its hard to discredit the dynos that show big gains on otherwise STOCK cars, but who knows once you open up the exhaust..

Id love for someone to go dyno happy once they get these LTHs... my one concern is though if you are tuned with a CAI, and you swap your stock box box and dyno , it really wont be right.. You would have to re-tune as tony has shown his A/F does stay pretty darn close to stock with just his exhaust mods. And the CAI def throws it off.. You would need a dyno, swap of intakes, re-tune, dyno.. Or a stock tuned car to do it, but with the ecu learning theory that may be discredited too.

Long live the CAI vs OEM air box debate!
