same issue. just flashed over the weekend. so far, power seems to be down a bit but overall it runs smoother. new plugs/coil packs as well. fresh oil, etc. all the other normal stuff is good as well.

so no noticeable burble at all. boost needle (on fuel gauge) seems to be showing good boost, but it just doesn't feel like it's making the same power as JB4 alone.

any thoughts?
