Blackbear Tune Reviews

Yes you will notice a big difference with your butt dyno. It will respond like you wish it to, not like GM originally programmed it. Especially getting the trans tuned to your driving style

Im ready to pull the trigger on the autocal tune for my 2016 Silverado. Im curious what my 1st step is though. I know they have to collect data from me driving my truck for a while. My question is...do i go ahead and purchase the autocal? Is the data collected through the hardware of the autocal?
