Every dyno I have seen including the ones this weekend have shown a loss. Also the cars have problems with dieing with the Injens as well. See my350z.com for loss power issues with injens.

Hey thanks! I noticed that your Injen is black and doesn't have the full extension! What influenced your decision to do that? I can understand not going polished because of heat soaking but the short intake with no heat shield I am just curious? Truplay if you ever want to sell your Pro-1 exhaust for sure let me know! I heard a sound clip you had up on here from photobucket it sounded sweet!! Also I checked up on the Injen power loss and a trend of power loss seems to be with the sedans, maybe the MAF is triggering something to the ECU who knows?? I also read a lot of power loss and poor reviews of the Stillen intake as well which was funny.. Looks like all intakes are just for looks

Yea i went with black to go along with the rest of my car. I went with the short ram set up bc down here in SFL when i first got it installed it was rainy season and didnt quite feel like hydrolocking and paying 14k for a new block. Ill let you know if i ever want to sell my pro-1.

Sedans and 350z but they all are the same car. Coupes are effected as well.

Where do you see power loss of Stillens? I have never seen one yet.

Russ,

A few members have reported low end loss via a "Butt" dyno. I have not seen any reported data to support this. I personally have not noticed any lack or lost of performance since installing the Stillen HFAB.

Wait a sec. You have data, which shows that the Stillen HFAB does produce negative yields?

No have data that shows Injens loosing power instead of gaining. I also have dynos that show Stilllen gains power.
