Mine is spot on on the tweak station and when you do the center chassis lifting. Of course, you need to use new tires or tires with similar diameter. I overlooked this one of those times and what a bummer ! I did everything like checking the shock rebounds, shocks lengths only to find out that I used worned out tires ! 
When tweaking, do you do like in the setup book? I've always adjusted the spring tension on the shocks at the end of the car where there is an imbalance (left to right), but the setup book says if the front is tweaked adjusted to rear spring tension.
Actually I start of by just looking at the front or the back by placing a hudy block under the other end of the car. Once the front and back are balanced, I take away the hudy block and then check the tweak again (front and rear).
