So I have 60s 2.7 duel pass option b. I'm contemplating a 50 shot to a 75 shot. Is that to much for a 2.7 with 60s on a stock m62? Obv will get a custom tune.

 

If you get a solid tune, you're golden. But just make sure the tune is spot on

 

You'll be fine, a 50 shot is almost not enough to need a tune, but it will help. If you are running a tune with highly advanced timing then yeah the nitrous is dangerous, but get a proper tune for it and you can run it forever. My car loved it.
