Perin CAI W/O tune! good or not ? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

JdelFrs · 03-02-2014, 11:55 PM

Hi fellows,

I just want to make sure, i know i should have just bought an drop-in :P but i already have it installed on the car!

here what is my situation : i am at 800miles on the car! i am looking to get an header + OP + FP and put my car on DYNO

.

My question is would it cause something big if i do like 4000 miles with the CAI by the time i get everything ?

With logic i would say no! but i would like some opinion

thanks guys/girls!

I drove my brz for a while with a perrin cai without a spesific tune for it.
No problem at all.
But this only counts for the 2-1/2" cai, the 3" version needs a tune.
Maf calibration will be way of with the bigger tube.

@Andreas83 is right, the normal PERRIN CAI is fine to run with a normal tune. Only the big MAF intake will require a special tune. The MAF table is available for that intake here.

So if i am going to buy an OFT, Running stage 2 on 93 octane gas, i should not worry with the normal CAI in term of long time ??

Since the normal one doesn't need to do a MAF scaling ?

Sorry, I'm not sure what OFT is. If you have the normal PERRIN CAI, then a map that's made for the stock intake will work fine.

The oft tunes are optimized for the stock intake. It will not be ideal for the CAI. Jamesm and some others have discussed how to adjust the maf. I recommend looking into it.

Got it, sorry! You might want to ask your tuner, but you should be fine.

Yea thanks every one

i think i will pass on OFT and go with a local tuner/Dyno - Custom Tune! I feel more confident in long run with a local tuner than OFT :P
