So you don't use the JB any more. Terry just came out with a new firm that I installed last night and he said it should fix the problem. But for some reason I feel the firm I had before it was better.
What is the firmware supposed to fix?any added power benefits?

And mine isn't installed right now because I've been lazy and don't want to install it yet haha
