    I have a 2010 mustang gt 4.6, Previous owner installed this Roush CAI...

    I bought the sct x4 and trying to file for my first tune but my CAI is not on the list.

    What to do?

    Also... the previous owner deleted the mufflers but the rest of the exhaust is stock, I dont see muffler delete as an option, will it be ok with no mufflers or will low backpressure cause any concerns?

    If you look on the AM page you linked to, it states, "NO Computer Tune Required". So, no need to set a tune for it. In general, mufflers are not a tunable item either. You can always call your tuner and verify.
