Check out the Rocket Valve, I don't know if it is still made but it was awesome. Mad Man Springs I think was the name of the maker.

As HobbesTZ suggested, the stock valve with proper springs will beat both of those in terms of efficiency and cost effectiveness.

I use a Maddman green mainspring,stock valve spring at about 300 psi with a Shocktech Phat Hammer. My gun gets 2200-2300 shots from an 88/45.

I'd go with either the MacDev red valve or the AKA tornado valve.

honestly,
I would hold out and put that new mq-valve on it if it ever hits the market. It will be $100 or so but if the videos are real and it lives up to it's potential, then it will be by far the best valve for the cocker as well as making it easier to use.

A tornado will give you the best effeciency , it will outperform any valve on the market, what is often the case is that in my experience the tornado needs to be sprung correctly to reach the proper performance and it needs to be mated to the lightening bolt. The supercharger vavle at least on initial inspection of the one I had in front of me is a pretty stock valve with maybe some slight differences.

Between the two go with Tornado. If you are not concerned about bleeding edge performance stay with the stock if you have it and if your stock is a recent year.

I run shocktech everything on my cocker. Rat valve, phat hammer, front end, springs, and supafly bolt. It runs great, but there are certainly valves that can out perform it.

I'd hold out for the mQ-valve if you've got an e-cocker.

Otherwise, Tornado is by far the best but not worth the cost. I'd just buy a new set of springs and call it a day.

Stock valve, sprung properly.

I completely agree. Stock valve and hammer, green valve spring, yellow mainspring.
