i would check what the lads have said

also are you runnig bump steer washers? ive seen people runnig zero bumps steer have the ball stud catch on the A-arm. this stops the car having full lock.

Also check your steering link, the large screws that connect the servo saver to the top deck if its to loose the lock car be forced back on power, also make sure its not to tight and straining the servo.

also check you slipper isnt to tight and causing the front to lift to much onpower

if thats all ok, try changing your rear end set up
shorter rear link, lower camber link pick up and outside on the wishdone will alow the rear to losen up.
