It could be that your throttle isn't working for both engines. Take a look at the throttle quadrant in the VC as you advance the throttles. Make sure they both move equally. Or you could watch the EFIS page to see what both engines are doing.I noticed this as well.
Try reducing nose wheel steer angle slightly in the aircraft.cfg file (CONTACT POINTS) but mostly reduce rudder effectiveness in FLIGHT TUNING section. Jets need very little rudder except or engine loss at low speed, otherwise mostly they are "feet on the floor".
If one throttle doesn't move evenly with the other, you need to troubleshoot that situation. Usually, it's a button or slider assignment problem. Another case that can cause the same problem, it's because your default flight was saved after you assigned the throttle slider to a single engine to shut it down for a cold-n-dark set-up.
Are you sure both engines are actually started and running before you start your take-off? Do you check over the EFIS page to verify this? If not, make sure you start the second, non-running engine before you start your take off roll.
Could it be a case of your rudder being hard over? Is the AP on and trying to fly the plane on a course other than the runway heading? Do you look at the external camera view, and verify the rudder doesn't do anything except what you command, especially during the take-off run? Watch it when you "wipe" the controls prior to advancing the throttles. Does the rudder throw full both ways when you wipe the controls?
Do you have a crosswind blowing? If so, try shutting the wind down, and trying the take-off again, and see what happens.
Just trying to think of possibilities, and this time of day, it's not easy for me. Not enough coffee aboard yet...

Good luck!
