The heat dissipation properties of a 300A controller modified to pass 400A is the same as it was when it would only pass 300A. (Same case and same heatsink area.)
Drop an Alltrax XCT48400-PDS (or larger) controller into it and hold onto your hat. If it is too fast or has too much performance, it is user programmables, so it can be de-tuned.
