You don't even actually need to cut it, that's just so you can adjust it without taking the whole thing appart. But yeah, don't take any loops off, you just need the path between the spring clear, so your tool can get to the adjustment screw on the NPAS.
In reality, I think the NPAS is crap, and if you want less FPS AND improved gas efficiency (which the NPAS won't giva ya), I recommend switching the floating valve spring (the spring you wanna cut). Most TM compatible pistol floating valve springs will do the trick.
What FPS do you want/need your gun shooting at?

Thanks Fox. The gun is shooting about 460. I need it to shoot at the typical range limits of 350 or 400. I'm a little new to this (you may have guessed) so not sure what you mean by "TM compatible pistol floating valve spring". I thought this was the only way to adjust the fps of GBBR's. Looking to do what works best. So any input is greatly appreciated. So, just to be clear, in the photo of the spring there is the little curly tail at the end of the spring. That is what needs to be nipped off but it is just so the tool can get in. If the little tail is not in the way of the opening then it doesn't need to be cut? What about the shaving of the lugs on. Also, if you want to elaborate the method you mentioned I'm very interested. What do you mean by "increasing gas efficiency"? Man, this is a great place to learn.
