This is a direct quote from an email exchange I had with
sales@vishnutuning.com:
Me: So with a Perrin cold air intake and bolt on I would currently use stage 1, and when the header is replaced, go to 2. Right?
Vishnutuning.com: Yes that is correct.
And again on a second occasion, when I asked about the Big MAF:
Me: Hi, I might be switching from a Perrin 2.5" CAI to the Perrin 3" Big MAF CAI, and I'm curious if I would be using the same map?
Vishnutuning.com: You should be fine using the same map. We haven't release a dedicated map for the 3inch intake yet.
So what got me started on all this was their use of the word "should" lol. And I say that the Perrin CAI is comparable to the stock box precisely because it makes no more power, but I understand what you're saying.

Any gains shown on a chart are most likely there by leaning out (unsafely mind you) the engine, which gets corrected after several miles of driving by adjusting LTFT's. Once you get your car tuned to operate safely with the intake, the majority (if not all) of the gains come from the tune and not the intake. My advice would be to sell the intake you have and go back to stock.

Yeahhh thats kind of where I was leaning. The sound from the CAI is great but I'd really rather have the performance.. and I figured "hey! why not try getting both with a 3" intake!"
But that all makes perfect sense.
