Balance shaft deleting, for economy?

So, I've been reading a little into modding my new to me Nissan, and there are apparently many ways to gain power(intake, header, exhaust, etc) it turns out that on the QR25DE engine, it's balance shafts are spun by their own separate chain, and that chain powers nothing else... I never really considered this on the Malibu I had, as the BS chain also ran the water pump, but Nissan faithful(Mostly in the Sentra SE-R crowd) claim a gain of 6-8whp by simply cutting and removing the balance shaft chain, presumably while the oil pan was off anyway due to rust(they supposedly rust out)...

Would this aid engine efficiency, albeit at slightly higher NVH?
