Depends on what your using it for. If you looking for anything less than a 400 shot from a kit...this one isnt really necessary. But you want to spray two 300 shots in stages with one set of bungs. This kit is the way to go. Hell....two 400 shot stages or two 500 shot stages.....1000+ HP total. I have seen this kit on a few door slammer cars lately in ProMod Cars making 2500 HP +. The car this kit is going on will likely be spraying anywhere from 300-600 hp on top of the 600-700 it will make on motor. We will see.

Ron....you need the new NX Maximizer II. It has provisions to set MAP parameter for spray. So when you launch it will spray progressively to what ramp you set...then cut out the juice at whatever MAP pressure you set. Pretty awesome setup. Spray out of the hole until the turbo spools to XX psi and then nitrous cuts out and turbo takes over.

I think every turbo manual car or turbo street car should run juice to cover those "vulnerable rpms" with something like the Maximizer II.
