OhioDoc:
I have a a dual stage set up if you are interested.
1.(2) NOS Pro-Shot solenoids and (2) fuel solenoid.
2. (2) NX Dual Stage Shark Nozzles.
3. Complete range of NX jets.
4 16' braided feed line.
The solenoid system is complete it is plumbed with (8) braided hoses. It now feeds into two chrome smoth tubes. Everthing sits on a single base that mounts between the smooth tubes. I set this up late in 2004, then took a different direction, in affect it has no hours on it. I also have single stage nozzles if you choose not to go dual stage.
All you would need to complete the set up is bottle and some relays. These are the high end NOS solenoids and the premium NX nozzles. If you are intrested send me an email. I can also walk your installer thru the installation. You can go on to my "My Gallery", there are pictures of the set-up.
As far as the window switches go, the MSD switch is adequete at best, it is inaccurate and fragile. As someone else has said, the VEC2 gives you more flexibility, plus, it allows you to fine tune your a/f, which is not possible with jetting alone. In tandem the window switch (via the VEC2) and a WOT switch give you a lot of safety.
