The problem is (or was) the rear springs are too soft. You can fix it by simply running stiffer rear springs.
I think the truck handles better with the 540 motor, but like Rick Howart wrote a couple of days back, if the track has a big double or triple coming out of a tight corner, you're kind of stuck running the 550.
