The ecu has been flashed to eliminate the emissions and tune for the velocity stacks, and exhaust system I have. But once the cams are installed I’ll have to reflash or run a piggyback to fine tune further. The closest shop with a good reputation for flash tuning is over a hundred miles one way. Just not practical in my area.
