Hey guys
I talked to someone the other day that told me my 09 GT wouldn't run right if I got an intake without a programmer. Has anyone done this and could you let me know how things worked out. Thanks

I'm gonna move this to the proper area.....

Not sure why it wouldn't run right, or why it's any different than that earlier years. I would check the websites of manufacturers who sell the ones that do not require a tune.

when I first bought my K&N I didn't have a tune. there was a small increase and I was happy with it. About a year later I bought the SCT and wow what a difference. !

A stand-alone, no-tune-required CAI SHOULD run fine on your '09 except that there are the few that have reported throwing a CEL for running lean. In other words, the PCM couldn't adjust enough for the additional air. Running lean can eventually cause severe engine damage. But even if it doesn't throw a code, you're not getting the benefit w/o a tune. A stand-alone CAI might net you 4-6 RWHP or so.

A tune required CAI and a tune (CAI & tune combo) from one of the better tuners (tune writers) will net you 15-25 or more RWHP. Even the custom 87 tune kicks major azz over the stock 87 tune.

a proper tune without a CAI would be more benficial than just a CAI by itself IMO..

(if) the MAF is the same size, all you'd be doing is sucking in hot air.. more of it lol.

^Im with him on the tune no cai would be better than cai and no tune...Most cai that don't require tune your not gonna get much...So get the tuner first no matter what...

He may just be doing it for the looks, and not performance.

Diabolical!

No-tune CAIs are not worth the minimal gains you get for the money.

I got mine from Brenspeed and did not put the tune on till I got home after 3 miles. The car had no ***** until I put the tune in if that is what you are asking.

And had you driven much farther with the CAI and w/o the tune, you'd have thrown a CEL.
