The wizards in the VESC tool are notorious for giving bad amp values. Keep in mind, the wizard does not know your hardware or application. If you want to maximize the performance from your setup, you will have to manually change your settings. Specifically:
Battery Amp Max
Battery Amp Min
Motor Amp Max
Motor Amp Min
Increasing those values will give you more performance, but generate more heat as well. Increase them too much, and your VESC may pop like a fuse. For more general help with setup and stuff like this, I encourage you to post this question here:
