New CAI and don't know what to do!!!!!!
I have a 2009 GT and purchased a CAI from UPR Products. I thought I would/ get it to the house and have it installed and increase my HP 25+ in less than 15 minutes like they advertised. Once the UPS man dropped it off and I opened it with much excitement, looked at the polished finish and ran to my GT with the box, I then set down by the tires and read the instructions. It read DO NOT INSTALL WITHOUT TUNING!!!!!!!!! Did I screw up by buying this brand? Do I have to take it to have someone tune it, before or after? Do I buy a predator or SCT tuner? Can I do it myself or is this beyond my capability? I want to put on some axelbacks after this, do I have to retune?
Ome more to add. Does this void my warranty? Is there a way to tune without the dealer knowing?

CAI's require a tune unless the manufacturer states otherwise (and even then a tune is sometimes needed to prevent throwing codes). You should have done your homework first. There's a lot of info in the forum about CAI & tunes.
A few of the best tune suppliers are Brenspeed, Bamachips, VMP and Tillman. They'll provide you typically 3 custom tunes specific for your car along with the handheld. Running a CAI that requires a tune will cause you to run lean and is not good for the engine.
Also, a stand-alone CAI will net you maybe 5-8 RWHP if you're lucky. A CAI & tune combo will net you 15-25 + RWHP.

Wrong, running a tune required CAI will cause the engine to run lean.
No so good. The cross section where the MAF mounts is bigger than
the stock intake and does not read the mass air flow properly.
A 'tune' takes care of this.

The vendors I listed above are excellent choices. They'll write custom tunes for your car specifically. They sell packages (CAI & tune combos) or just the handheld with the tunes preloaded. They'll also be able to e-mail you new tunes as needed to support tune-required mods.

Like stated contact a tuner like Bama or brenspeed and have them send you a tuner and 3 tunes. You will love it.

if the MAF housing is stock size, then it should be okay to run without a tune from what I hear, but with some of the other ones (85-90mm) you're gonna need a tune or you'll run lean and run like crap. The combo kicks ****.. I just returned mine to stock because i have to take it to the dealership for work and wow.. what a slug it is! fack!
