Check out some of the setup sheets on Associated's site. No guarantee that any one driver's setup will work for you but you may see some trends based on the types of tracks they are driving on. Secondly, have you checked what the locals are doing? It may simply be the wrong tire or wrong tire prep for that track. The reason I say this is I've tried a number of setups on my TC6 and none of them had problems with a push.
Good luck.
ive basically printed every set up sheet i can find to study sey ups . Yesterday when practicing i wasnt running any tire treatment i started with sorex 28 and were worse then my hpi 30 but still had pushbutb was better when i switched. wasnt sure if i adjusted roll centers if would help also checked my camber last night and was noy equal side to side.
