What is the total HP output from the Toyota Highlander Hybrid, I mean mine feels powerfull and all but 400 ft/lb torque seems a bit much, so how do I add the electric motor torque along with the gas?

Where did you get 400 ft/lb torque? The HiHy has max 268 hp and max 212 ft-lbs. torque.

Because I added torque from the electric and gas motor together

They do not provide that torque at the same rpms, so the combined max torque is 212 ft-lbs.

The 212 ft-lbs max torque is by ICE only.
The max system power is 155 kW (ICE) + 45 kW (battery) = 200 kW or 268 HP (combined) .
We can see 252 ft-lbs torque from 200 kW at 5,600 rpm.

Thanks. I'm still having a hard time finding out what the maximum torque is. According to these specs, the electric motors alone combine for 343 lb.-ft. at low rpms.

I think highlanderhybrid was closer to the answer in the first place. I was the one who was wrong. Sorry.

Here are the torque curves for the Highlander Hybrids engine and motors:
