Smell started at 18K miles (now@25K). Only mod is CAI/ 93 octane tune and American Thunder Flow Master axle back...That's it.
Cat temp control update tune has been installed and it went away for a few miles...it's back.
It happens every time it's rev'd past 6000+ RPM's (never past red line). After a 120-150 MPH run, windows have to come down to let rotten odor out...goes away quickly.
Immediately after the :nono:...spirited drives. I get out to see if there is any smoke in the engine compartment...nothing.
Other problem...nothing to do with spirited drives. I use this car for estimating parking lot repairs...if it idles for more than 5 minutes. Check engine light comes on (lean code). Code is erased and continue on my way.
Rather than messing around with FORD Warrany rejection...seriously considering letting someone else inherit this problem...no control of who buys it after it's traded in.
Got rid of my 2010 GT500, so I could drive a Stang without worrying about depreciation. Now, I have GT aggravation :yup: need a solution so I can continue to drive it for a while...HELP or it's gone!
Don't even mention that I need another car for estimating its my company car preference...to hell with econo boxes.
I would ditch the dam tune,go back to stock and see if your problem goes away, Ford doesn"t like them either,the only tune you need on the 5.0 is the one that comes out of your radio,and that"s no stink.

Of my many problems with my 2011 GT when new, I too had an oder. I brought it to the dealer who later found a burning sticker on one of the exhaust pipes (or so they said). Apparently, when the pipe got warm, the sticker/adhesive would heat up and burn, sending a foul smell (smelt like something died) around the vehicle.
The dealer removed the sticker/adhesive and sure enough the smell went away.
I would do a quick check to see if you have a similiar issue.
I honestly cannot say where it was for sure except somewhere on the exhaust system. My only advice is to look it over as best you can to see if that is the problem.
Mine just did that yesterday. I was around redline tried to shift into 4th and the damn thing wouldnt shift so had to shift into 5th. Noticed an odd smell for about a minute couldnt tell whether it was the clutch or the cats.
What does it smell like? Mine has a little bit of a burning smell if I get on it. Has since day one. Just turned over 1K. I figured it was just normal break in smell.
Thanks for all responses, been on vacation...^^^^exactly what it smells like.
It's a lot better since STEEDA revised map (cat temp control). But the odor has not gone away completely. Not worried...car runs fine under normal driving conditions.
Car is daily driven 200+ miles a day with at least one-two 120+mph runs :yup:.
I think I would be more worried about the lean code than anything. Something is not right there, maybe they forgot to load the correct values for your CAI. Return the car to stock (tune and CAI) or talk to the guys at Bama about another tune.
The described odor used to be common when catalytic converters just came out, and usually occurred during cold starting, and older cars after hot running. These were carb-era cars and the smell was undoubtedly due to inefficient fuel delivery with fuel not completely burned in the engine and forming deposits on the converter.
You've described long idling, lots of daily driving and a custom tune followed by Autobahn speeds. I suspect the tune may be the cause.
