Dealer flashed my com and I don't have my tune anymore.

I noticed when the meds kicked in because I had turned that off.

How can I put the tune back in?

And I can do this from this tuner?
How would I modify it? I'm new to this

I'm using BP 93 octane and this is my first time doing a log.
I have knock around 5,000 rpm 1.5 degrees and around 6,000 2.5 degrees. Should I switch to the 91 tune with the 93 fuel I'm using?

What's the big difference between the 2015 and up wk2 tcm tunes?

Has this been released yet?

I am very new to this tuner where would I find instructions to show me how to post up the tune.

What do I need to do to get the custom tune for the codes?

I'm going to the exhaust shop next week.

Last question I've heard some guys getting codes with stock tune when they delete the exhaust drone valves in the rear.

Do I have to worry about that with this tune?

OK cool I was wondering if torque management was changed.

I just got my tuner I wanted to know what changes were made to this tune vs stock?
