I feel the increase in induction noise was very noticeable, especially at part open to 3/4 throttle in the lower RPM range

To the OP...

Was the replaced BMC filter clean when you switched? How many miles on it?
The BMC filter had about 5k miles on it and was pretty clean.

I was skeptical as well but the dyno never lies, especially as I was watching the numbers being put down in real time.

Exhaust and a tune would result in even higher power gains.
No problem, Tom! I think my car may break into the 400HP club with a full exhaust system and a tune.
I didn't build it hoping for your approval, I built it because it meets mine
