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.
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.  |
I guess what your definition of fine is. Will the standard off the shelf tunes be able to handle the trim adjustments needed for the 2.5" CAI from perrin? Sure, but your LTFT's may be all out of wack. Will it run? Yep. Is it ideal? Nope.
As for the 3" intake, I find it hard to believe that @
shiv@vishnu would say that running the 3" intake on a standard OTS map would be fine without some form of MAF scaling adjustments. Even if you only modified the maps with the provided scales from perrin, that would be better than nothing at all. I'm fairly certain he's getting married this weekend so I wouldn't expect an answer directly from him for a bit but maybe he can chime in here when he gets a chance to clarify.
