The Lyra2v2 timings are depended on a good coreclock/memclock and boostclock (no trottle'ing)
The problem is when I mod a kernal to run fast on the 960, it might hurt the 970 performance.
When I mod a kernal to use more power, cards with little power will start to trottle.
The cryptomining blog has compared the 20 last sp-mod versions on the gtx 970:
