Well I put the performance tune on my truck the other night to try it out. All I can say is hell yeah!
Its got alot more get up and go, also keeps speed on the hwy while on cruise going up a hill, which it didnt do before. It is by far the best thing I've done to my truck performance wise so far! Think with everything I have done to it, its all working in harmony now. 5.2 ftw!
