To be honest, I don't like to use other racers setups. I would go back to completely stock on both trucks, then drive it on the track. Make minor adjustments in whatever it is you feel you need more or less of and test again. ONE THING AT A TIME. Be sure to make notes on what you changed.

This takes time, but if you get it down people will start asking for you setup one you get dialed in to your driving style!
