thanks for finding that, thumper. i was asking if any other tuners can check your a/f ratio.

 

I don't believe so. Although even with the Livewire you'll need the wideband sensor.

 

ok. it says i need some kind of sensor to go with it in order to check it. what is it and where can i find it?

 

just wanted to post what bill said. i called him today and he said that for most normal air intakes, k&n and AFE, i would NOT need a custom tune. but if i were to use a homemade CAI or something like that, then i probably should get one.
