I just finished up a BTR stage 2 truck v2 cam install in my 2009 Sierra all terrain 5.3L & needed to tune for it. James Pruitt was suggested by several. So I contacted him before the cam swap to have a remote tune done when I was ready..... I can say I’m very happy & he exceeded my expectations. The truck was somewhat stock before cam swap (k&n cold air & flowmaster muffler). He saved me headaches & more time than I can only imagine & im sure I still would have needed to have a remote tune done after struggling to get it close to acceptable... If anyone is on the fence about having a remote tune done... James Pruitt is definitely a reputable/professional guy & will exceed one’s expectations.
