<div class='quotetop'>QUOTE(thunderwagen @ May 30 2007, 11:10 PM) [snapback]95336[/snapback]</div>It depends on the a/f ratio meter and how often the shop takes care of their equipment. I religiously changed out my widebands once a month to ensure they are reading correctly. I've seen some shops have the same o2 for a year, lol. All that heat and gas eventually destroys them.
By the way I took it to a buddy of mines shop the other day and put it on his dyno so we could use the air fuel sensor on the dyno. Come to find out it is not lean at all. As soon as it goes wide open it dropped below 10:1 I dont know where it actually was cause the AFR on the dyno doesnt go below 10. That was with the O2 sensor in the down pipe too. Oh well we will get it worked out sooner or later.

If thiers was reading that much off, I'd stick with what we saw on the brand new FAST unit and brand new wideband we were using.
Regardless, come on down someday and we'll double check it.
