Hello everyone,I am facing a little problem with a friend of mine who apparently tried tuning his 2008 Toyota tundra (5.7) v8 but it seems everytime he tries to flash the vehicle it goes back to stock like he didn?t change anything at all is this usually the case with Toyotas I know about gm mostly but I am not familiar with Toyota is the reading and writing method different here or is it just locked and needs to be unlocked and sent to you? Any info at all would be appreciated.


Thanks
