hey all, i'm looking to purchase a commercial solution to tune both my 2018 silverado (5.3/6L80) and 2019 suburban (5.3/6L80) after the 6L80 in the suburban grenaded itself after only 92k miles and 4 years....

is it even possible to buy tunercats any more? it looks like they actively sell seed keys and definition files on their website, and a cable called the "dealer kit", but no actual tuning or logging solution?

it maybe seems like they sold out to a company called jet DST, but to be honest i cant even figure out how to buy that?

anyway maybe its not in the running anymore, i could just buy HP tuners but between the MPVI and the credits for those two vehicles, i'd be looking at close to 800 bucks....ypres!!
