Im guessing its because I dont have an LSD and under hard acceleration all the power goes to the right rear wheel but the car normally pulls/pushes hard to the left under acceleration.

I would think that the any imperfections in the roads surface would cause this!
The road may seem flat but the tires will see it differently!

i have 1200 miles on the car, hopefully not yet. It happens almost everytime I accelerate HARD, i feel myself compensating for it pulling to the left

happened to me...

i live in NY, have a C2 Coupe, with summer tires, if i take it out, and its less than 45 deg outside.. if you gun it, the car will pull a bit to the left.. best bet.. either get winter tires, or take it off of the road for the winter..

So its because of not having the LSD?

It could be alignment, tire pressure, or as Stacy said the road (crown, grooves, etc).

I didn't have this problem before my LSD.

Does the car pull when you are not accelerating. I would think that it could need an alignment. Look at your tires do you see uneven wear patterns. Run you hand accross the tread of the tire can you feel feathered edges. You tires should tell you the story with your alignment. Quick fix check your tire pressures. Next have the suspension inspected or have an alignment.

Tires rotated? You do not want to do that on a 911.

This isn't a limited slip issue. Remember, the power will go to the one that loses traction without a LSD. However the Brake Biased diffy on the 997 will compensate for this. Also, this will only be an issue if you are breaking the tires loose. If they aren't spinnng the car shouldnt be pulling to either direction. FWD cars will do this as this is called torque steer, but RWD cars don't do this.
