Way too low. At 34 you should be around 25-26 on the subsonic. Take your port frequency and divide by 2. Take that total and divide by 2. Take your port tune (34 in your case) and just subtract the last total from it.....that's your subsonic level.

You get the same result by multiplying the port tuning frequency by 0.75.
