Likely, the KB chip isn't the correct strategy.

I'd normally tune a 2.1KB like yours for more around 19-20 degrees on 93 pump at the 9psi. KB will likely push a little more. I'd also shoot for an AFR around 11.6-11.8. On my Mustang Dyno, the base intercooled 2.1 kit is worth more like 450 RWHP. I'd run it all the way up to the redline to ensure that fueling and timing are correct. In terms of the knock sensors, I'll eliminate the KS ability to add timing but let it take up to 3-4 degrees when it needs to. This is assuming that you tuner has mapped the edge of borderline knock.
