I have a gen 2 6r80 with an ngauge Lund tune, my shop said I should reflash my tune, how do I reflash a tune do I simply just load the tune over again ?
After reading this whole forum, I’ve went ahead and purchased the Solonoids I don’t believe it could be the o2 sensors cuz they still show readings and I imagine if a o2 sensor goes out it won’t read at all and I don’t have a check engine light for it or anything at all not even for the throttle...
