I have ran my EZ off and on for a couple years. I took mine off for good, a couple of months ago. I have a buddy that had one also and he ditched his for a Smarty. Both of our EZ's, would throw P0192 codes (Low Fuel Rail Pressure) it would pop the fuel limiter valve on the fuel rail and they also hung on acceleration. (When you let off there is a bit of hesitation before it stops accelerating and start coming back down). I would recommend a Smarty or Smarty Jr.
