Long story short, the Zex 82238 nitrous kit can not be made progressive. I had planed on going progressive with a Nos Mini, max 100 shot more then likely 75 shot though. So what I need is opinions on those of you running a straight shot and those of you going progressive. Pro and cons would be cool. I have the controller and I only have a short time to return it. Also if I forego the Zex NMU what will I need to convert it in order to go progressive. Thanks for the help.
