What sort of track are you running on? The Reedy race was held at a very smooth indoor track.

Are you suffering on power push? I would suggest the following:
- go to 2 limiters in front shocks
- add some weight to the front (~10g in front of servo will help) and move the battery forward

As always, most important thing is to make sure you have the correct tyres for the track before trying to change too much on the setup.
