Default car sucking

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?

Sounds like you have a rich condition. Check the air filter for dirtyness, and maybe re-flash but I can't see how a tune is going to change over it's lifetime unless of poor quality.

How long has this been occurring? The last tank or 2 of gas? Had a friend that got a batch of fuel that smelled like a gas/kero mix and his car stunk and ran like crap. If not, I'd reflash first as mentioned above.

Normally I'd say change the plugs, but our plugs are stupid expensive.[:@]

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

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!

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.

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.
