does anyone have issues with takeoff power being too low when departing with toga thrust i do all the calculations in mcdu but i always struggle to rotate (salty mod) i cannot empty any stab tanks as their aren't any to empty?

V2 calculated by FMC Takeoff page seems too low to me.  VR is way off.  I set V2 to 8-10 knots higher than calculated by FMC, subtract about 7 knots to get VR and type those numbers into the takeoff slots on the Takeoff page.  V1 is just a guess depending on runway length and weight of aircraft.

With the Autothrottle on, the engines are slow to rev up to selected TOGA thrust.  I now keep the Autothrottle off and manually push the throttles to maximum. 

Sometimes I've noticed the engines rolling back in Climb mode instead of maintaining Climb thrust.  Again, controlling the throttles manually, Autothrottle off, works.

I don't understand your question about "stab tanks" or what this has to do with takeoff problems.
