Has anyone used one of these? do they work?

 

I have the NOS mini dual stage progressive controller. Its awesome! Its not just a progressive controller, it has a window switch, and digital rpm gauge built in and has a remote with led display. I use the remote to change the parameters. I can go from a 100 shot to a 50 shot in about 15 seconds. Its sweet! I did burn up one solenoid but it was junk anyways (nx mainline) so I switched to NX lightning solenoids and never had a problem. The problem with the mainline solenoids is that there is no plunger I dont believe. Theyre totally different from a standard solenoid. Anything like NOS,standard NX, TNT, or Dynotune solenoids will work great.

The feel is great. You can really tune how your car makes power. I was running 10hp at 3000rpms and ramping it up to 100hp by 4500rpm. It came on smooth and pulled like a blower. Now NX has came out with one that does all that AND adjusts the spray by how much boost you are making. Its sick as hell and I want one.
