Anybody verify their air fuel ratio after installing a mail order chip? I was just curious how close these things were. Friend was telling me how a mail order chip could reliably set AF to 11.2-11.5 every time on these '03 Cobras, since production characteristics are so consistent. Personally, I'm skeptical.
Anybody ever verify the things?
Thanks,
CW
