like the title says, looking for any reviews from people who have had the jb4 on the trucks for a while now.

trying to pick what tune to go with. jb4 has always seemed simple on and off on my past bmws.

if anything, ill just go cobb but i have the jb4 app on my phone already so thought might as well look into it
