I don't know where your ordering your tune from but Bama will automatically turn off the rear O2 sensors in all their tunes. I am looking into an offroad h pipe myself and e-mailed Doug to see about having my tunes modified to accomodate it and he told me that I am already set as he turns off the rear O2 sensors on every tune specifically for the reason that so many people add offroad h and x pipes.

 

ya i will be getting my tune from bama. Cant wait. Does anyone know the normal lead time on tunes?

 

pretty quick, i've never waited longer than 4 days
