I had some issues with my SF as well. After the install my AF Corrections were up around 10 spiking into the 20s at cruise with my AFR spiking into the 17s. Took it off and everything is back to normal. I sent cobb an email, I anticipate they will just tell me my cars fxxx'd and not their product... Wondering if I should just send it back.
