I think I got really lucky. He replied overnight. Blessed but yes I think people can just forward the email for others to download and extract then change the name of the tune.
Im at 700 miles on my 2018 si. Drove it hot off the lot like I stole it. My psi show 25 psi max with the 19/23 base tune on sports mode. I have not even come close to slippage. Maybe just lucky.
