Last Monday I received my spe hot x tune for my 2013 6.7 powerstroke. I know that these transmissions can hold 600 hp for a long time! And this tune doesn’t even make 520 hp. My transmission is gone after 1 week. 1 week. 200 miles on this tune. 93k miles on the truck. I emailed them about it. And they said “we have not quite heard a complaint like yours” bs I’ve been researching and looking online. And I have seen multiple threads of people with this same issue. Beware. There trans tuning will destroy it, in nothing flat.
