Search this and other forums and you'll clearly know that even the no-tune-required CAI's can throw a CEL for running lean. The PCM's simply can't adjust for the additional airflow.
Stand-alone CAI ~ 4-6 RWHP
CAI & custom tune combo ~ 20-25 RWHP
Even a good custom 87 octane tune will run circles around the stock 87 tune. Find another shop. And BTW, you load your own tunes. Don't allow a shop to handle that for you.
(I'd be rich if I had a nickel for every time I've said that...)
What exhaust did you put on? The stock exhaust flows very well so ANY changes from the OE H-pipe back will only yield sound improvement; no power addition.

but as for the exhaust I installed was an axle back exhaust from flowmaster the idea of it causing a problem did come across as a possible problem but I from myself and the shop came to the conclusion of it not being the problem but you never know sometimes.

Well you're going to have to make a choice, either get a tuner (custom preferred) or go back to your stock air box until you can get a tune to properly use the CAI.
Just FYI, tuning isn't what it used to be. You don't just go work some wrenches or work physical parts, it's all done through the on board computer.
And BTW, I hope you mean do it yourself as in plugging in your hand held onto the OBDII.
You won't regret spending the money on a tune.

The AM page for the CAI that you supplied the link for says that particular CAI requires a tune. AM is very good about putting that on all of their CAI's. I had a V6 and put a K&N CAI on it w/o any problems. It is one of the very few that doesn't require a tune. It looks like you'll either need to get a tune or see if you can return or sale the CAI you bought and get the K&N. By the way, I ended up buying a tuner and tunes from BamaChips and could tell a big difference in the K&N.

ya no I did check before I bought the cold air intake that wasn't a problem because I had already have a place in mind to install it and check it all about before that they could do it what the failed to mention was that they didn't have the right tuner for the job so until I get a tuner I have to end up returning it and getting it later until I'm able to purchase it. As for plugging the hand held in I know what you mean its a lot easier then it used to be which is a good thing because it makes it easier then before it seems even easier when you get the touch screen

You don't do your own tuning with the exception of being able to tweak a few settings. The majority of the parameters that truely affect performance are not user adjustable. That's where a quality shop writing your tunes comes into play. Brenspeed and AM are 2 of the best. Al lyou need to do is plug n' play.

Why do people call these custom tunes? Aren't they really just canned tunes? A custom tune is a tune that is done at a reputable shop on a dyno where the guy writes and uploads the tune to your car and it is SPECIFIC to only your car, not uploaded through the email by some guy that has never even seen yet alone touched your car.

Custom tunes are written for your particular PCM with your particular mods and any other changes you tell the tuner that you want. These are about as close to a dyno tune as you can get based on the tuners' experience and your wants & desires. Too often, folks don't tell their tuner what they want (which can lead to a bit more of an aggressive tune if they did) so the tuner simply does his best to give you a good tune.
A tune done on a dyno is a dyno tune and usually provides SOME improvement over a custom tune. Depending on the aggressiveness of the custom tune and the dyno shop's capability, the improvement can be significant or it can be only a few ponies. I've read where guys have reverted back to their custom tunes after getting a crappy dyno tune.
