XXX4 issues

[dan02gt]

I have a XXX4g+ with a MM4600 and 3c LiPo. The car works well on my off-road track, but does not do very well on the paved road or high traction surfaces. At any time I try to get it up to speed even under just moderate acceleration the car becomes uncontrollable it will just pull to the right hard. The car it in very good running condition and well maintained so I don't think there is a mechanical problem. I also don't think its glitching. I'am using just a standard JR race servo for steering and I'm wondering if maybe I'm getting toque steer. I have also noticed than when I hold the car in the air and punch the throttle the front wheels do turn a tiny amount to the right. Any ideas?
