So for the $800 that we would pay for this, is the tuning included? Or would it be a separate charge through someone else? And would the tuning here only modify the downpipe/DPF info?

I am trying to figure out if I can just order the downpipe and install and then have Evolve or RENNtech flash the ECU with this info so that I get performance and DPF bypass.
