This is a dyno sheet from another member Baer383. HP expectations for this kit should be in the 500+whp range. I had several small boost leaks when I had mine on the dyno and that limited me to 7.5-8psi. So I have no doubt it was getting closer to this HP after fixing them, it as a noticeable gain in power, but never got a chance to get her back on the dyno.
