I'm hoping someone can give me some advice on continuing with this tune. We have a relatively stock 5.3 with a 70mm turbo limited to 7psi of boost. I spent a lot of time reading through previous posts and how to's in order to get started and to get where I am. As of now, it is running a 2Bar SD tune in open loop. As of last night, the first pull seemed to go quite well with no knock but by the last log, it started to develop some KR. Any advice would be greatly appreciated. (Sorry, if I'm doing something completely wrong let me know. I'm learning as fast as I can being my first attempt at this.) Thanks in advance!!
