2006 Mustang GT - U7140, Failed Emissions Test... Now What?

Windveil Blues

OLD FART
This kind of surprises me, as I have always been told that the tunes were 50-state smog legal. This is what I posted on the Diablo site earlier today:

"Post subject: 2006 Mustang GT - U7140, Failed Emissions Test... Now What? Posted: May 29, 2008 - 10:55 AM

I have a 2006 Mustang GT and a U7140 (v.8r36), and the car just failed emissions testing in Missouri. Other mods include FRPP ceramic shortys, FRPP x-pipe (CATs intact), JBA axle-backs, UDP's, Airaid CAI, Predator Airaid 93 octane tune and 4.56's. Any idea how I can make this thing pass?

Any help would be hugely appreciated.
Thanks,

Jim"

Any ideas anyone?

Thanks,

Jim
