Thanks for all of the advice. I did notice the air hissing after it left which also indicated to me it was not be realeased quick enough. My question now is what do I use instead to increase the airflow/ how would i mkae my own QEV valve. Thanks

What would you recommend changing to get a better flow or better performance out of it?

Check Out my instructable for pretty much all the info. I also posted a youtube video of a few tests I conducted with it.
