Hi
i have yukon denali 2016 and now im tring to put back the original backup back but when i do that the device reboot and nothing happen .. what should i do ?

and when i set a new car should i choose 2015 ?? because if i choose 2016 there is no GMC

i want to do the 91 Octane Performance Tune is it possible ?

then if its not supported yet why on your website shows that it can be done !!

why do you say that on the website its working and let me buy it and then i discover that its not supported yet

this is cheating

Hi
i just bought the Trinity and i want to use it on my car but for 2016 its not showing except Ford ?

so can anyone tell me how can i do it ??

thanks
