More noise after 92/92 install

Is this common? I installed my ported fast 92 a couple days ago and haven't had a chance to get it tuned yet. The noise level of my of my sewing machine increased a bit since...

Any one else experience this?

Totally normal as far as I know. I have read many report this in external so may wanna search there.... My fast went on with H/C and it was louder but obviously I had other variables..

I ended up with 24 hp and 26 ft lbs of torque over the ls6/ported tb and the tune is perfect. It runs like stock - no joke. trap speed went from consistent 116 to 120. I know that's a huge jump but i'm not complaining.
