Can I stack an edge ez with my Smarty beta 4.4? If so what levels would you guys suggest on the edge? Thanks

 

You can stack the EZ. The beta 4.4 adds some pressure already, but will stop around 24k depending on the truck. I would suggest lower levels for every day, turn it up at the track.

Reminder, increasing pressure on a daily driver will also shorten injector life over time.
