So I just happened across a BBK 70MM DBW throttle body on eBay for cheap months back. Was planning on doing some sort of upper plenum, when/if I ever plan on doing the install. What my question is, is a tune required? Obviously to get the most out of the setup, a tune would be necessary. Should I just wait to get a tune before doing the install? I've heard conflicting answers on this. I would imagine, that a properly functioning MAF, should more than adequately learn the new airflow capabilities of a larger throttle body, no? Shouldn't effect driveability?
