I am going to install a set of headers on my 2008 Z06 w/1.75" primary tubes. The only other mods is a Halltech Killer Bee, the tune is stock. The question is do headers make the A/F ratio rich or lean? The other question is are there any hand held tuners that adjust A/F ratio for headers? Unfortunately we do not have anybody in my neck of the woods with a dyno.

TIA

I would guess that it will lean it a little, and most of the hand held tuners should be able to adjust the ratio. I'm not a tuner, so we will have to wait for one to chime in.
