Guys there is no proof as far as gains and losses with the other intakes so let it rest. Until someone does a before and after dyno then people need to stop listening to what Cobb or anyone else says. Stillen and Fujita all show dynoes of gains along with Injen. Does that make it true? Maybe and maybe not. Until someone does a before and after dyno to prove this then let this subject rest. Anyone with a Stillen or Fujita intake is probably happy and that is what matters when you mod your car.

 

Dieseldoug's dynos at Technosquare have a comparison of the stock airboxes (black) vs. Fujita intakes (red) before they reflashed his ECU:

 

So there is some proof on the Fujita lossing power, finally. Thanks Buddy Revell. Looks like HP equals out at 5900RPM and gets better at 6600RPM for the Fujita over the stock but below that is losses power. TQ is a loss everywhere. That blows.

But it looks like the Fujita is better than stock with an ECU reflash. Does anyone else see that?

 

looks like 15whp gain with TS reflash and short ram intakes...not bad for around $800.

had tadashi reflash my Z and it was definately the best power mod for my car.

 

the 14whp if event true is prob on a stock g37...when combined with ur FI exhaust and HFC's I would imagine that it would fall a few horses.. (eg maybe 8-10 peak from injen)....I dunno I'm no expert but it's just how I've seen mods react in the past.
