[QUOTE="Strokersace, post: 1565159, member: 622"] I ran proven on my 2014 and again on my current 2015. Zero issues with the trans in either. Shifting is spot on. Much much much better than the unknown tunes my ‘15 came with. Trans now performs exactly like my 2014 did. Maybe I’m just used to shit trans tuning??? [emoji23] doubt it, but if enough know it all facebook warriors complain about proven enough then they’ll drive down sales and make people think (that haven’t run them), that they’re junk. [emoji1787][emoji1787] There is probably better out there. But I’m pleased on the 2 personal trucks I’ve ran them on. Power is spot on and show have the transmission manners. [/QUOTE]
