Seafoamed a few times on a 23K mile car?? [&:]
+1 to Gidyupgo - You're running RICH
Stop with the unecessary seafoaming, you're just gonna eat your seals up. Check/clean your plugs, replace fuel filter, Clean or replace your air filter, reflash your tune (your car adapts over time) then see how it goes.

So my 2005 GT with 23K miles seems to have sluggish performance... Extremely full of sootishness in the tailpipe, thick. Bad gas mileage.
I have CAI + bama, cmdp, loudmouths, DS, shorties,have seafoam cleaned a few times, nothing special.
Ideas?

Your tune doesn't adapt over time or to your driving style...

He's getting too much fuel.
Be it either from not enough air, bad tune, or an incomplete combustion process. So, re-flash, clean air filter, or replace plugs. That's ALL it could be.

You should still change the fuel filter if you haven't changed it yet.
It's probably just in your imagination more than anything. I would put the car on the dyno if you think it is feeling sluggish and then go from there. The soot is definately there beacuse of your tune from bama which is from adding more fuel, but does not necessarily mean you are getting too much. I'm sure that could play a part in your gas mileage having a more aggressive tune, but again put the car on a dyno and record your gas mileage after each fill up!

The soot in the pipe indicates he is getting too much fuel, not starving it.

It could mean this, but that is not a FACT. When you add more fuel, you will have more build up on your tips. You can say the car is running rich all you want, but that doesn't mean he is losing power.

Well, obviously if the spark plugs are fouling, or the exhaust tips are sooting up, it is too much fuel under the given conditions. Next thing to go will be O2 sensors.

RE: car sucking
He needs to pull the plugs out and check or get an air/fuel reading which is why I said get that **** on the dyno! 
It could definately be the tune if it is a mail order file and could definately be running rich in that case.He definatley needs to pull the plugs and check for build up but that is all in his hands.

Cough wideband cough...lol j/k thats my answer to all questions now. If I have a problem, my wideband is going to show it most of the time. The guys here seemed to have covered all the basic things it could be. Always start with the easy/obvious things first, you know that.

On the 05+ with throttle by wire it does adapt/learn. 04 and older don't have the same ignition, ECM, or PCM system. Older stangs are simply "plug and play".

RE: car sucking
Soot can mean the mixture is rich, but not only. It could also mean the fuel getting to the chamber just isn't being burnt completely, so yea, I'd say check your plugs.
+1 on it being imagination as well. I find that washing and waxing the car makes it feel like it's gained 50hp, try that
