Solid gains through the power band. I have an active autoworker mid pipe and will likely add their downpipes soon. I'll tune it if it ever gets bench unlock able or something not to difficult.

So map1 i’m assuming? Good to hear that you had experience with flashed cars and you’re still happy with the JB4!
