Louder engine after dyno

Hey guys. In the quest to have my bike (which I've owned for maybe a month now) running as good as possible, I picked up a couple of goodies and took my bike down to a local reputable dyno tuner. I swapped out my Victory Performance filter for a Lloydz high flow filter. I also added the Lloydz timing gear and the bike came with Vance and Hines pipes when I bought it. My bike had the "typical" rattle sounds that I've read about but not bad and the V&H exhaust sounded really nice. I dropped my bike off and had them install the Power Commander V when they dyno'd it. When I picked it up I noticed the engine noise was MUCH louder. The engine noise is so loud now that I can barely hear the nice throaty growl of the exhaust. I really dislike it. Is this normal? If not, any ideas of what it could be? Thanks for any help you guys can offer.

@Tinman413 Its hard to say from your description if there's an issue or not. Its not abnormal to hear some more engine noise after the upgrades you did but it shouldn't be drowning out your V&H exhaust.

The timing wheel is set to +4. I put the gear in before the dyno. The bike seems to run fine. The exhaust no longer pops as much either. But it does sound like a big obnoxious chopper. I don't like a quiet bike by any means, but I do like the smooth sounding power.

Could what you are hearing be described as intake roar?
When you install a Loydz filter you remove a baffle under the tank that will cause you to hear the air being pulled into the engine. The fairing makes that noise even louder...

Or has it developed an intermittent ticking sometimes increasing in volume till your sure your riding a a hay baler, then returning to a mild ticking again?
That is a problem with one of the cam chain tensioners or a dirty lifter.

Wait...! What oil are you using?

In all seriousness, as I've said before, "I'll start worrying when I don't hear engine noise..." I've also noticed over the years that the engine will make different noises at different times. Other than the normal valve noise, sometimes it is chattering like hell, other times I hear a more whiny sound and once in awhile it entertains me with a "bicycle chain" type noise. Its all sort of random, nothing ever happens so I keep going. One thing I can say is engine noise gets more pronounced when I get close to oil change mileage.

I actually switched to Rotella T6 the other day. It already had the exhaust and I added the Lloydz air filter and timing gear BEFORE getting it dyno'd. Bike sounded "normal" right up until I rode it into the shop. As soon as I fired it up when I picked it up later that day I noticed the much increase in noise. Let's say for comparison reasons that my bike used to sound like my V8 Tundra with the Flowmaster, and now it sounds more like my straight piped older diesel! I'll call the shop. I've never had a bike dyno tuned so I didn't know if the significant change in sound was "typical." Looks like it isn't. Hopefully I get this figured out. The shop said my bike tuned perfectly with no issues. BUT he did say it was one of the few because lately the dyno machine has "been chewing bikes up!" I wasn't aware of this fun fact until after the fact. I appreciate all of you guys taking the time to try to help me out!

A dyno tune in and of itself is not going to make your bike sound a whole lot different. It sounds like something mechanical.

Not that I think I could diagnose the potential issue based on feedback from this but others with more experience can figure it out....

Is the new sound consistently growing louder the faster you go in a linear manor?

or

Does the sound get louder or grow more intense with relation to the RPM's? No mater if you're sitting in neutral revving or from the bottom to the top of each gear?
