Sea foam and hesitation are most likely not related.
I would start with checking/cleaning Mass Air Meter and associated connections with change of CAI
After reading some of the other posts, I may have mis-spoke on this, I assumed you used additive to engine oil, but instead you may have been talking about adding to fuel. Sorry I might have been on the wrong page. If you added it to the fuel, it most likely is related. Any concentrated cleaner added to fuel could cause partial clogging of injectors which will impact the spray pattern thus impacting performance.

I'm getting more confused with this by the day but I do really appreciate everyone's input.
After driving for a few days, here's what I know for sure:
Hesitation is almost random - when it happens, the car falls on its face between literally 1800 RPMs and 3000 RPMs.
Runs perfectly 1st thing in the morning and for an hour or so - I can get on the interstate after the car has been running for 5 - 10 minutes and it screams with 0 issues.
Worst hesitation occurs after parking for a sales call and then coming out 20 - 30 minutes later. Seems like a "heat" related problem - are fuel pump issues sensitive to heat?
It has 81,000 miles - should the spark plugs be replaced anyway due to mileage?
There is a TSB on the fuel pump and I used to have the classic issue described after cruising - so should this not be replaced anyway?
Could some of the causes of my problem been there the whole time but now be pronounced due to the extra fuel/spark demands of the Steeda CAI and SCT 93 Tune.
Would returning it to stock definitively prove anything if the problem is what I said in the previous bullet point?
Final Point - I have never spent so much time trying to get a $700 mod to actually work as intended.
1) Shouldnt take long to return to stock to see of that is indeed the problem. If it is you will stop seeing the hesitation, if its not you wont.
2) If theres a TSB and you havnt had it done I would get the fuel pump taken care of and go from there.
Do those 2 things first and you'll be ahead of the game, your out of warranty so I guess that wont help but I dont believe it's your spark plugs otherwise you'd see the issue be more consistent I would think.

No sh!t!! that's some BS IMHO. Did your miss in your work truck cause a vibration? I have a vibration at 3200, most noticeable in 3rd and 4th. I was going to try and buy 1 spark plug and injector from a FI guy on here. That way i could swap them out 1 at a time and see if it solves my problem.

81k on stock plugs? I would change those for sure. At the very least I would pull them and check them.

Yes it caused a vibration and a studder and once I was at higher rpms it cleaned up Vibrations can be cuased by way to many things

I truly appreciate everyone's blood, sweat, and tears on this one.
UPDATE: Absolutely HEAT related, period. As long as the car is moving and air is flowing through the engine compartment and enhancing the cooling effect ALL is good....Stop and park for 10 minutes and let the heat soak begin. Not sure what's "heating up" but something changes. Drive for 5 minutes over 50 mph and all is good again. Ditched the throttle body spacer tonight just to simplify what's going on. Re-tuned with lower fan turn on temps. Drove and ran liked a scalded dog. Didn't park and turn off and then run again...will see tomorrow.
Regardless, will swap all plugs and fuel pump. However I believe the CAI (and install of) and Tune is fine.
For those that were following this thread.......the fuel pump has been swapped under warranty by a dealer here in Atlanta......problem still exists, though not as bad. IT ONLY HESITATES UNDER MODERATE TO HARD ACCELERATION WHEN IT HAS SAT PARKED FOR A FEW MINUTES AFTER DRIVING....HEAT SOAK....LET IT RETURN TO NORMAL TEMP WHILE DRIVING AND IT RUNS PERFECTLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
.....WHAT IS HEATING UP? IS THE MILLION DOLLAR QUESTION....DID NOT DO THIS PRE-CAI AND TUNE...
Did you ever remove the CAI and tune? Common sense would tell you that's the problem if the problem started right afterwards.

Moosestang - Thanks for the reality check. I really don't want to F with that but it looks like I'll be doing it anyway. I just don't understand why it runs PERFECTLY until it's parked for a minute. Thanks!!!
I don't know, but tunes can be funny things. If you do put the stock tune back in and it runs perfectly fine then my suggestion is to get a tune from brenspeed.com or B@m@chips.com for the steeda intake. That way if there's a problem related to the tune they can work with you to fix it.

Seafoam, lol. 80k miles NO problems, use Seafoam & problems, but it cant be the Seafoam, right? Soooo many people have problems after useing that crap but insist that its not the Seafoam that did it. LOL
FrostByte - I'm not saying it's not the SEAFOAM...that's why I asked originally. Do you have anything to support what you're saying? I just want this BS done with.
It just seems that alot of people have NO problems w/ it but there are alot that have problems like yours after useing it. I have read too many threads like this one. I wouldnt use it myself, if I thought I had to I would only add it in the gas tank.
Take the fuel rails off the injectors. I bet one or two is clogged. All that crap the Seafoam loosens up has to go some where. Change your fuel filter also.
It appears beside having a vehicle with some miles on it you have two unknown variables (what everyone has pointed out) the CAI and tune and the Seafoam. Lets face it the problem started after these two events. I think you need to start removing variables as everyone also said. if you remove the CAI and tune and still have the problem then it is not that variable, in which case you can look at the Seafoam. I think the only reason everyone is suggecting attacking it from the point of the CAI is because it's the simplest. If not the CAI then it is most probably the Seafoam in which case pulling the rails and such will probably be in order.
In other words start with the CAI and hope that's what it is, because the alternative could be quite a bit more involved.
Wow, I think I just repeated what you said Hammeron. However, I think you said it much simpler!

Thanks Guys! Kevin
Did you check your temperature gauge when this problem occurs? Is the car running hot? Are you sure the low speed / high speed fan settings set properly on the tune you have installed? What are they set at?
