OP, it is very possible that this dyno has a calibration that is just somewhat low. You are worried about a difference of 30 WHP which equates to 8-9% of the reading. It's not easy to imagine that kind of difference from a dyno. It may be out of calibration or maybe the calibration is slightly off.

Basically, without a baseline, we can't tell you whether you are seeing the expected gains from your parts because the dyno is a bit of an "unknown".
