Gamo whisper fusion pro tuning?

Hello all,
I have a Gamo Whisper Fusion Pro in .22 . Is there anything I can do to make her shoot a bit quieter? I stuffed the stock with okld t shirts but I was wondering if there are any tuning kits out there. Not looking for speed just overall smoothness.
If there are no kits available , is there anything else I can do from home to improve shooting experience?

A self tune that you can do yourself should tame it down some. Check the GTA Library for articles explaining how to perform a tune yourself at home. Lot's of good information in there.

I am shooting jsb Diablo, around 18 grains.
About an hour ago I completed a DIY tune. ( or attempted one I should say)
I took the synthetic stock out. To my horror, as I was taking it out some metal stuff started dropping right and left. I was like " too late now".
First I noticed, that on the other side of the buttstock, there was a small hole , which I could stuff the stock even more. So I did, with a long flathead I started shoving in there 2 pieces of foam and then cotton cleaning patches. Then right in front of it, there is a small chamber roughly 1.5 inches long. I stuffed it with cotton patches as well.
I then sprayed the trigger mechanism with a dry lubricant spray, the same that I spray the uniballs in my trucks suspension. No reason but I thought it can't hurt. Then, I took a brush , and started brushing the portion of the spring that I could see with blue grease. After I figured out where those 2 metal tabs that fell in the beginning belonged to I assembled the rifle again.
I only shot 3 pellets after that , but my impression was that the twang was gone.

Also I would like to give you guys some crony numbers. I performed the test a few days ago:
I put through the crony my air king 54 and the Gamo whisper fusion pro, both in 22, both shooting JSB heavy, 18.13 grains. The air king 54 is tuned by John in Philladelphia.
Gamo:
698fps, 697, 703, 695, 692
Air King 54
698fps, 702, 687, 694, 699.
I was impressed on how small of a spread the Gamo had. That being said , shooting the 54 and the Gamo is a night and day experience.
I am shooting both without scope and I am much more accurate with the 54. ( which is also much more quiet).
I am attributing this to the fact that I still haven't mastered the artillery hold and that the Gamo hasn't had more than a couple hundred pellets through it. My groups with the Gamo at 20 yards shooting with the sights spread around 3-4 inches.
I am curious to see after the "tune" if the chrony numbers have changed or the grouping improved

I would experiment with different holds, perhaps a firmer grip.
