I've searched and can't find a file like this. I built an LQ4 into anLQ9 and have a Crane cam with very similar specs to the 04 LS6 cam. Very mild exhaust port clean up done also. The motor went into a 40 Ford and runs good but I know there is more to be had. A file like that would be a great starting point for the guy doing the tune.
Anyone got one I can use?
