Ok fellas I know you all are the pros, I just bought a new 2017 highcountry with the 6.2/ 8 speed. Apparently no one can tune the tcm, so I decided to buy a diablo i3 since I’m familiar with it, was gonna go BLACKBEAR but they refuse to answer emails or phones, so here’s what I’m asking!! what bolt I s Can I buy to get the most out of this truck, I’ve read I should not swap my manifold to the vet manifold or the msc due to losing mid range and that since I have the 8speed it won’t matter much. However let me know your opinion? * what cold air intake * what throttle body upgrade * should I upgrade manifold * what are the best header option * I already added the cat back borla exhaust * am I missing anything, I’m gonna start buying ASAP so LLEASE HELP
