Has anyone used the Cold Fusion brand nitrous kits? I have been looking for a 150+ HP kit and considering the Sniper, Nitrous Express, Nitous direct and Cold fusion kits. They all seem to offer "basic" kits with around the same power ratings and price. I want to get a good system that will hold up, but get a good deal too. The Cold fusion kit is advertised at up to 200HP so I figure the solinoids may be bigger/higher flow and it would allow for me to go up in power as I get everything sorted out. Any input on any of these kits (as well as others I didn't list) would be greatly appreciated!
