I don't know maybe I had gotten used to the old intake but it got going between 60-90. I remember on the freeway I pulled away from a 3 Series from 60-85 and then of course he got away after that and I wasn't trying to get a ticket either.

No, on the contrary. The more additives, the less gasoline in gasoline, quite literally. Your engine does not burn additives, it burns gasoline. Adding anything to it lowers the amount of gasoline per given volume.
We can not get straight oxygen add-ins here (at least that I've been able to find), however, Shell V-power (premium) does contain Nitrogen. That's the best we get, and it's more of a cleaner than anything.No, on the contrary. The more additives, the less gasoline in gasoline, quite literally.

Those additives are of course inevitable, especially the ones that increase the octane rating. But the less of them, the better (in terms of power output). In other words: for maximum output you should use the lowest octane No allowed by the engine manufacturer.
There's one exception to the rule above - gasoline with additives containing oxygen. Not sure if those are available in the USA. Oxygen improves combustion, so this is the only additive that actually increases your power - not by much, but still. It gives the same result as driving in winter, when there's more oxygen in a given volume of air taken in by the engine.
Hope this makes sense... If not, I'll try to explain better next time
Having re-read what I have written I decided to add: this is all true when we talk about trying to maximize the engine power output here and now. But the additives in modern fuels have another, important function: to ensure that the engine will still output its rated power a year or five years from now. I'm talking about the cleaning agents added now to pretty much all commercial fuels. They don't help maximize your power today, but they slow down engine age-related power loss.
Losing power and risking injuries to its exhaust/catalyst system...
I don't know about them anymore this will be their what third tube.? Maybe they should have just waited it out like corksport or something.
I agree. They seemed to have rushed it.
Oh that's good news, lets hope one of them works. I don't think there are many other intake options on the market.
I saw information on another forum and called Injen for an UPDATE on Wednesday (09/18/13). Since I already had purchased the intake (SP6073P), I asked for an update on the replacement. They informed me that the REVISED version will be available in two (2) weeks. I was also informed that they will replace the main tube unit at no charge for those who already own it (and implied that the existing one will NOT be needed to be sent back). So IF you already own this, please find your receipts in preparation to provide proof of purchase for your replacement. Based on the conversation, you should be able to call INJEN (TEL 909.839.0706) on or after October 2nd, 2013!
Well it's October 3rd now. Anyone have any updates? -- I'm still with my 2004 Mazda, but I'm curious to see the aftermarket develop for you guys with the 2.5L Skyactiv engines...you should be able to call INJEN (TEL 909.839.0706) on or after October 2nd, 2013!
