I recently bought a savox digit 4096 servo for my AE SC6.1, and on centered trim it goes full left. But, if you reverse it goes full right. I have to set my trim to full to the right to keep the tires straight, and it still want to go to the left a bit. What can I do to fix this? Do I need a servo checker? Any help would be great.

Disconnect your servo horn. Turn your radio and vehicle on. Center all steering trims on your radio, reinstall servo horn and make small adjustments from there.

Sounds like you hooked everything up without initially centering your servo.

I also like to adjust the turnbuckle between the servo arm the ackermann to make sure the car is perfectly centered, I don't use any trim setting on the radio when initially setting up a car to go straight. Also make sure the lengths of the turnbuckles on the steering links are perfectly equal, use a caliper to check length.
